Thanks, Charles and Paul!
Put the Bush Spices w/Mountain Pepper and a little Lemon Myrtle on the roasted cauliflower tonight. Might have been OK, but I drizzled on some Balsamic vinegar when they came out of the oven. Overpowered the spices. Next time, roasted carrots with the same spices - no Balsamic! But, I did a hasselback potato with the Tasmanian pepper salt, with some extra Native Pepper seasoning. That was nice. Mountain pepper has a very unique flavor. Spicy in kind of a anise/fennel or nutmeg kind of way, but more subtle.
