I actually wanted to ask Sarah and other knowledgeable people here if there is any harm / benefit from instantly putting my dehydrated veggies and meats into freezer ziplocks and freezing them right away.
I just did that to a batch of blueberry leather (just mashed blueberries).. my trip isn't for another 4 weeks and the maildrop will be opened in 6-7 weeks from now, so I figured I should keep it frozen as long as I can.
Another idea was to pack the ingredients for my meals separately in the maildrop, so I can throw something out if it does go bad.
for eg, my most common meal uses these ingredients:
grated parmesan cheese (like Kraft)
dehydrated veggies (asparagus, green peppers, green onions, carrots and maybe tomatoes)
dehydrated ground beef w/ onions
My initial plan was to mix the right amount of each of these together so there would a complete meal in each ziplock bag.
But now with the talk of mold and all, I might pack the veggies for 5 meals together, the meat for 5 meals together and so on and mix them on the trail.. or at least after opening the mail drop.
