You are a downright gourmet, making biscuits Probably you know all that I have to say already, but I'll throw in my 2 cents.
I do like to "cook", but that usually just means, for eg, making a Dr McDougals instant soup cup (which is a pretty decent and cheap base) of whatever, but then adding a little olive oil, minced garlic, cheese, maybe a tiny bit of minced carrots or red bell peppers or some sun dried tomatoes. I always opt to make it soup because it's easier to clean and avoids sticking, and besides, I like soup.
Couscous is something I use regularly, but you shouldn't have to cook it over a fire: just add boiling water and oil/butter/ghee and maybe some other ingredients and let it sit covered, no flame. Maybe do a quick sautee of the added ingredients first before adding water and bringing it to a boil.
