No heat instant/emergency food?

It took me three goes to make ones i was happy with, i am a very poor cook. The trick is to start preheating the oven as your very first step, then measure out ingredients and mix them etc, so the oven is warm enough the moments the biscuits go in.

He says cook briefly at very hot and then optionally dehydrate at a lower temperature for a long period of time; i have a gas stove and i've never successfully just made them at the brief hot temperature, they have to go in the full time.

They're made on a griddle (thick frying pan) not the oven. Dries them out fine. I've made them once, they need quite a lot of fat & are very high calorie count. I ate mine while around in the house not walking, and put on weight immediately. They were fine but as you say, a bit of practice helps.
I'll certainly use them if I'm going to do any strenuous pack walking. I'm minded to try it with some cooked smoked dry fish, like mackerel or kipper fillets. I think that will travel well and fits with his historical period context.
