Starting your freeze dried food pantry. 100 Days: The first 50 batches - Freeze Drying Your First 500 lbs of Food
Start by asking yourself this question. Why are you freeze drying food? Knowing this should help you decide what you should freeze dry first.
I'm freeze drying because:
Just to freeze dry leftovers?
You want to make your own food for camping/backpacking?
For if/when the SHTF?
For a short term emergency?
You have your own garden and want to freeze dry the food?
You love Costco but don't have a family of 6?
You are good at finding the food sales but only have 1 freezer?
When you cook homemade chili just for yourself you make 10 gallons? Because you have 3 full freezers and are worried about power outages?

This list is about getting started on a 500 lb mixed pantry of freeze dried foods in 100 days.
(This may be a bit optimistic and perhaps it'll only be 400 lbs)
Goal of about 85 lbs per category. (100 lbs per category if we don't do the Meals/Dishes)
1) Meats:
2) Vegetables:
3) Fruits:
5) Grain / Starch
6) Meals / Dishes

Freeze dried food will stay fresh for many years and be ready and waiting when you need it.
We do videos showing how we are using our Harvest Right Freeze Dryer to freeze dry food for long term storage. (We have the medium size machine that we got in August of 2017) Freeze dried food is also great for prepping or just for camping and snacking!
