I like the idea of dehydes, but I'm a student and the cost of dehydrating in terms of bills is prohibitive. No complaints, very lucky to get anything at all but living on a total of $250pw not including rent or bills is difficult.
Anyway, having made and optimised Coke-can ovens, I found they're excellent with some tweaking. A simmer version may be made by adjusting the size of the vaporisation chamber larger - my simmer version stretches 15ml of metho to around 8min of low-velocity simmering goodness, including priming.
Add 300ml of water, and two packets of the Cup-a-Soup soup of your choice. Simply simmer, stirring, for maybe 7-10min, and you have reduced it into a very serviceable sauce for dehyde rice, topping for toast etc. Also excellent and nutritious with a tin of tuna. Add some more water and the dehyde rice directly for a one-pot meal with protein, carbs and a lot of taste for maybe $3, depending on if you buy your produce on sale. I can make it for $2 by stocking up on sale items.
Enjoy! I like Thai Laksa.
