Here is the story of the grape-nut ice cream-
Grape-Nut ice cream is a popular regional dish in the Canadian Maritimes, the Shenandoah Valley, Jamaica and New England. One origin story is that it was created by chef Hannah Young at The Palms restaurant in Wolfville, Nova Scotia in 1919. She created it when she ran out of fresh fruit to add to ice cream, and decided to throw in some cereal. It proved popular at the restaurant and the Scotsburn Dairy company began mass-producing the ice cream variety, and it sold across the region.
I've been doing that for ages, grind my own chuck beef roast and add some spices, no binders, and loosely form the burgers. Set up for indirect cooking and that's it. I know it takes a long time to cook (45 mins.) but I really like them that way and I haven't gotten any complaints. They are moist tender and tasty not to mention there is time to sit and relax. I always set them up with my needle probe so it's just a case of sit back and watch the temp., don't have to open the grill until I'm ready to put them over the fire. If you try it I'd be interested to hear what you think.
