I've dried anywhere from 12 to 25lbs of Roma tomatoes. Pack those in savory olive oil.
I can't imagine rehydrating an entire meal for home. Out in the mountains, sure.
Instead,
I'll cook for 10-15 servings, eat some and freeze the rest.
Do that 10 times over the course of a month and the economy and timing really pay off.
Example:
#1 = 3 x 14" pizza. My crust, my sauce, the toppings I like. Each cuts into 8 big slices.
That's 24 slices, total. I eat 2, maybe 3. Freeze the rest in pairs.
#2 = Chili con carne': 3lbs ground bison and fixings will make about 15-18 servings.
#3 = economy tray of 8 big chicken breasts. I breaded and baked them all. 2/3 is a serving for me
#4 boneless skinless chicken thigh. Tray of 12, poultry seasoning core in each. Baked = 6 dinner servings.
I've done travel camping with guys who pack up, totally frozen.
What we eat depends entirely on what thaws out first!
I suppose you could try drying anything and everything I've mentioned.
I think that the food would be ruined.
Sure if you could freeze-dry it all, it might move up from pathetic to terrible.
Dry ingredients that you know will not otherwise keep. Fruit and vegetables in particular.
Get a cure and a rub and ground beef and make 1/32 mile of jerky.
Pemmican was dried and smashed bison meat mixed with bison fat, done up in 60 - 90lb bison hide bags.
The precise documentary records of the Hudson's Bay Company show that Rocky Mountain House,
a fur trading post, had to prepare 44,000lbs of pemmican for the travelling fur trading employees.
They did all of that in just 9 days each year.
Bonne appetit. I buy a side of local bison every year. I got the fat. I rendered the fat and made pemmican.
I was instructed by First Nations Elders. Now maybe you won't starve but I'd almost rather eat bird's nest soup.
