You can freeze dry soy and almond milk as well as most non-dairy yogurt, sour cream, and cream cheese substitutes. This has been especially helpful in avoiding food waste, as my son is the only one who uses the non-dairy substitutes, and he rarely is able to finish them before they go bad. I just throw them in the freeze dryer for him to eat later.
