I've been converted.
Herb with cookies taste so fine, so so fine. Made a log of rosemary cookie in the afternoon and freeze the rest of the dough.
Another good idea is to freeze a few logs of cookie dough (of different flavours of course), so when there's company or cravings. Just slice a couple and bake. Freshly baked cookies anytime!
The dough keeps for a few months if kept frozen, the idea of it is fantastic.
Lemon thyme is next on the list, and perhaps a few other. But never ever lavender, its equivalent to putting perfume into your food. Yuck.
