  1. At the moment the two most recent threads are spam, 5 and 10 hours old, by different posters. There are dozens of people here I would trust with the authority to delete threads, under a "one strike" rule: If any deletion is even remotely a judgment call, as determined by our actual admins, that authority is permanently revoked. None of these spam threads would last 30 minutes, under such a system. I'm going to take a break from posting until we sort this out.
  2. It's a Ranger, their smallest fire pit, but much bigger than their camp stoves.
  3. May I ask, what is the rack? I want one!
  4. I ordered the Fourneau mat, which fits on my mini pizza peel, and doesn't need handles. I do own scissors, but do the BreadMat-C handles get in the way of closing the Challenger? Once I toss in three ice cubes, I feel like I'm on a tight clock. Steam does make its way between the Challenger pieces and the knitting of the Challenger gloves. I've never been burned, but I don't feel like waiting around! As in, any extra step that takes another half second would be dumb. They do say two ice cubes, but they don't specify a size. Huh. Their handles are to overcome the difficulties in lowering an unbaked loaf into a tall-sided Dutch oven. A solid border prevents deforming the loaf. However, the Challenger doesn't have tall sides, and readily accepts my mini pizza peel. Do the handles stay up, so they're never in the way when one replaces the Challenger lid?
  5. FOURNEAU 2.0 SILICONE BAKING MAT Yes, that mat is approximately 11.25" x 6.75", and the Challenger interior dimensions are 11.5" x 9". So that would work!
  6. Katakuchi Suribachi & Surikogi Set Last night's KK cook was a pair of white arrugula pizzas. Arrugula from our garden, that wasn't going to wait. We like a crisp, almost cracker crust from whole grain, as one approach to pizza. Last night I made a small change to my technique, that I quite liked: Dress the arrugula with the olive oil topping, and spread onto a dry pizza. This was easier than tugging oil across the crust itself (yes, not that challenging, but this was noticeably easier). It seems the crust had more chance to breathe as it baked. I briefly microwaved a few cloves of garlic, and mashed this in my favorite suribachi (I have all three sizes but I regularly gift the middle one as most used) with olive oil, preserved lemon, black pepper and maras pepper. If one leaves out preserved lemon, add salt.
  7. Stainless Steel Pizza Peel With Collapsible Rosewood Handle Relays could work, but they call it The Challenger for a reason! Their suggested directions are to preheat at 500 F, put in the loaf with a few ice cubes, reduce the heat to 425 F and bake 20 minutes covered, then 12 minutes uncovered. I flip the lid and put the base on the lid. I find that these directions work well for a range of breads. Sometimes I rotate halfway through the 12 minutes uncovered. Sometimes I go 15 minutes. Sometimes I flip the loaf bottom side up for the last few minutes. I've been working with 80% hydration, 95% extraction doughs from freshly ground grain. This poses challenges; I generally bake cold from an extended fridge ferment. My loaves would stick without parchment paper underneath; I use the above mini pizza peel to move them without damage. I've tried removing the parchment paper at the 20 minute uncovering mark, and the loaves still aren't completely set. I now just let the parchment paper ride, perhaps up to the final flip. In practice, one can't adjust KK temperatures this rapidly, and one often doesn't want to run an indoor oven longer than necessary. I find that once The Challenger itself reads 425 F using an infrared shooter, we're good to go. With the KK, I'll arc high and ease down to target temperature. So you could run a relay pipeline, if you have a stone or steel that fits next to The Challenger, while maintaining a constant baking temperature.
  8. I now have three Gilson test sieves, purchased over the last decade. The #20 arrived yesterday, so I made some careful extraction estimates. We have an older Wolfgang Mock Grain Mill, that most closely resembles (and takes the same replacement stones as) the KoMo Fidibus 21. A comprehensive US source is Grain Mill, Flour Mill, Grinder | Stone Burr, Impact & Steel Burr Mills at Pleasant Hill Grain. They also recommend the Royal Lee Household Mill if one's exclusive goal is the finest possible flour. I would contact them for buying advice; the newer Mockmill 100 & 200 probably represent the best value and performance, if one is not put off by their appearance. I adjusted my mill to grind as finely as possible without gnashing stones, then tested one and two passes of 500g hard red winter wheat from Central Milling, with each of my sieves. The extraction percentages are shown in the above chart. One can buy Gilson sieves from sources such as Amazon, or directly from Gilson. It's worth consulting Gilson first, to understand options. ASTM Test Sieves | USA Standard Test Sieve - Gilson Co. What is a Sieve? Make Sure You Choose the Right One - Gilson Co. 12" Sieve, All Stainless, Intermediate Height, No.20 - Gilson Co. 12" Sieve, All Stainless, Intermediate Height, No.25 - Gilson Co. 12" Sieve, All Stainless, Intermediate Height, No.35 - Gilson Co. These sieves are expensive but remarkably well-made. They fit perfectly into a Vollrath 69080 8-quart heavy-duty stainless steel mixing bowl, universally available from restaurant supply stores and Amazon. These bowls are the best quality I know; we have multiples of many sizes. I have a friend who cheaps out whenever he thinks it doesn't matter to free up an extra $40 for one night's wine, and his wife is still gnashing her teeth that he didn't get Vollrath bowls. The quality difference is striking.
  9. I mentioned the Solo Stove in a different thread I think the branding is all wrong on these.... This thread starts slow as we all learn. I thought I should update it with my current practices, that have been stable for years. I still use my Solo Stove all the time.
  10. As my off-brand POSK disintegrated, my wife bought me our 23KK. I didn't put up much of a fight. She was tickled to talk with Dennis; people should consider putting uncertain spouses on the phone with him. I wish I had his charm. I wouldn't go bigger, doing it over again myself. I've fed 80 people out of my 23KK. Two zones? My KK is my oven, used most often for bread, pizza, Focaccia di Recco, roast or tandoor chicken, and monumental smoked meats. My Solo Stove Ranger is my grill. Sometimes I'll be smoking pork for carnitas in the 23KK, at the same time that I'm grilling vegetables for salsa on the Solo Stove. I have a Weber kettle we haven't touched in years. Kettles are a fundamental design, brilliant for their day, but one can now do much better. I now associated kettles with the taste of burned chicken fat, guests in someone else's yard. Worst case they make me do the grilling on a mismanaged fire, like a pitcher left out to take one for the team. I can set a fire in my Solo Stove in a couple of minutes: wood chunks, lump charcoal partway up, a splash of 99% isopropyl alcohol, throw in a match, then come back in 30 or 40 minutes to a perfect fire. The vertical, smokeless column of hot air combines all the hype of air fryers with traditional grilling over fire. I get much more uniform cooks than I've even seen anyone get with close-to-the-fire grilling, and better flavor. Mine is a Frankenstein rig (a Breeo Outpost adjustable grill grafted onto a Harbor Freight service cart) but Solo Stove has caught on to cooking on their fire pits, and offers some interesting options if one spelunks their site. They recommend wood as a fuel, concerned that a full load of charcoal could get too hot, but one never needs a full load. I layer wood then charcoal, as wood lights faster but charcoal lasts longer. There's a long KK Solo Stove thread. It starts out slow as we experiment, but has more information.
  11. Wow. I had thought of pitching all the bran into the levain to digest, as a way to stay 100% extraction, but I hadn't tried it yet. Bran slices gluten, and you're moderating this. Yes there are many factors influencing starter flavor. Temperature, hydration, timing, how much to carry over. Desem is a famous corner of this design space. I’ve been favoring lively starter at the expense of other characteristics, but I’ll get more confident. By expanding the behaviors we can offer, the real purpose of the Sourdough Home is to engage us in a relationship with our starter. As one wonders after tasting bread how baking technique and the recipe might influence its flavor, one wonders after smelling starter how handling technique and the recipe might influence its aroma. These involvements are twin aspects of naturally leavened bread making, on an equal footing. I sometimes think that these involvements are a scientific process for reaching an objective result. I sometimes think that these involvements themselves are instead the whole point, and imprint on the result exactly like other art forms. Paintings can reify thought, transferring part of the painter's inner world to a degree that can shake one's soul. Science can't explain this transference. People talk of a "passionate" cook? When one travels, why is eating the food so important to understanding the culture? When food is magical, it achieves this same kind of transference.
  12. I've logged 221 loaves of bread since 2011. After a long initial struggle trying to understand why freshly ground "green" flour didn't work, I settled on a sourdough recipe that was roughly half freshly ground hard red and rye flours, and half bread flour. I used some yeast to boost the sourdough, and worked through at room temperature on the bread's schedule, overruling mine. Every time I tried to work out a new recipe with these basic assumptions, I ended up back with the same recipe. This is true of so many things: Considering how hard I've worked at this, you'd think I'd be better. One's first reaction to the Sourdough Home could be that it's a convenience for feeding starter less often, without inducing a fridge coma. A more nuanced read is that fermenting bread can be every bit as subtle as fermenting wine, and the Sourdough Home is a tool that increases one's options. Mine provoked me to relearn bread with new ground rules: all freshly ground flour, nearly full extraction naturally leavened with no yeast cool phases to extend the fermentation time and allow more flexible scheduling My original inspiration was Desem bread, but I've evolved into a new equilibrium recipe. Above is my eighth try, and I'm starting to get the hang of it. We love the taste. My loaves are far from Instagram-craggy, and far from anything we can buy in the SF Bay area. My new several day protocol is this: prepare a levain from flour, water, starter hydrolyze the remaining flour with a few conditioners I expose the second mixture to a minute in a chamber vacuum machine, which accelerates the hydrolyzing process exactly as others use vacuums to marinate meats. Let both mixtures rest till the levain is ready. It's convenient preparing both mixtures at once, and the long hydrolyze gives the conditioners time to act. Combine these mixtures with a salt water solution Stretch and fold in a bowl, frequently for the first few hours Transfer to the Airscape glass canister, mark the level with a grease pencil, and place in 50 F Sourdough Home Wait another interval, typically overnight Pull out the dough, let return to room temperature and rise 20% above grease pencil line, typically 3-4 hours Bench rest, shape, place loaf in proofing basket or box Wait 2 1/2 hours, frustrated that the usual signals for overproofing don't seem to apply. Move the loaf to the fridge. Wait another interval, then get either the KK or an indoor range up to temperature. Bake cold from the fridge, typically in a Challenger Bread Pan. Baking cold from the fridge is a convenience that supports more flexible fire management, and it stiffens the dough so it won't sploof out so much. The additive I've settled upon are 2% vital wheat gluten 0.5% diastatic malt 60 ppm ascorbic acid For me these make a dramatic difference. Everyone's results vary. If you buy flour, even freshly milled full extraction, different ballgame. This is not Desem, but it's healthy.
  13. Yes. I owned and gave away the Lodge Double Dutch Oven, recommended by various books and predating the Challenger, because it only made boules. I considered and rejected the Fourneau Bread Oven for exactly the downsides they note. The Challenger just works, and it bakes bâtards. I used to always bake a pair of loaves and give one away, which favored my aluminum disk in a cake pan for steam. I now bake one bâtard at a time, which favors the Challenger. The KK appears to handle my steam method just fine, but when we spent more than my first two cars on an Italian range for our kitchen, we blinked. We'll still use my steam method for free form baking in the KK, but like @Pequod the Challenger has become my default both inside and in the KK.
  14. The Challenger Bread Pan is an effective alternative to filling an entire oven with steam. They're the same idea as the Dutch oven approach, except one gets to bake a bâtard, which some of us prefer to a boule. They recommend a couple of ice cubes. In a KK, the bread then doesn't see fire till one removes the Challenger lid. That's ok; for us the main advantage of the KK is avoiding heat in the house in the summer.
  15. Actually, what I realized was that aluminum has nearly twice the specific heat capacity as steel, so I replaced my steel chains with an aluminum disk. Thomas Keller is the earliest reference I know to using rocks, which I consider a clumsier approach than an aluminum disk. There are two pervasive problems with web debates, both raised by The Perfect Loaf. First, they need content, so they'll write something. Second, many people will assert that they're happy with an intermediate solution, and all they're saying is that they're happy. Partly because they're unaware of better solutions, and haven't tried them. The Perfect Loaf certainly doesn't compute the physics. That is a time-honored approach: Try something and see if you're happy with the results. Of course, many people claim to be happy spritzing 5 grams of water from a plant spritzer. That's a placebo effect. What I computed was the weight of aluminum needed to create enough steam to replace the volume of a KK or a conventional oven a couple times over. This is what commercial bread ovens do, because they can. What I don't understand is the marginal utility over generating just enough steam to partly fill an oven once. That certainly helps over doing nothing. It's amazing how in a weak bleach solution, bleach finds its target. I don't believe that a weak steam mixture behaves the same way, but my chemistry days are long ago.
