Had some questions about ingredients.
How long do powdered eggs and powdered milk last once the container is opened? I made a few premade biscuit / cornbread type things and want to know how long they will keep. Also with leftover powdered eggs/milk that I am not taking on the trip should I store that in a freezer? Vacuum seal it?
Vegetable shortening – if I want to use shortening in my baking (vs oil) can I just mix it with my dry ingredients before hand without causing issues?
And in the “not a question” category, I did enjoy some nice cornbread when testing my steaming setup in the kitchen. https://goo.gl/photos/jKExLT8ohbkmAkkq5
