These are mixed a couple of days before the trip. The flavors will not last if mixed then stored for weeks.
Instant potatoes mixed at home with all of the following ingredients added to the same batch:
veggie imitation chicken stock
shredded Parmesan cheese (haven't tried the powdered ones)
Nido dried whole milk
a little hot curry mix for a hint of flavor, not an overpowering curry flavor
dried basil, powdered by rubbing in your hands
dried parsley powdered as added
On the trail, put in a water proof container, add cold water, stir and set to let the flavors blend. This is stoveless--instant spuds do not need hot water.
Quick oats mixed with powdered cocoa mix, cinnamon, nutmeg, all spice, light on the cloves, Nido milk, butter powder. At home, add drops of almond extract and vanilla and stir into the dry oats. Take the flavorings of your favorite cookies and try to duplicate that in the loose quick oats. On the trail, add water, stir and wait 5 minutes. This is stoveless--quick oats do not need hot water.
If the trip is long enough, buy a small jar of peanut butter. At home, spoon out a full core sample from the center. Slice an 8 oz. package of cold extra sharp cheddar cheese lengthwise into a 1"x1"x6" log. Shove the log into the center of the PB jar. Refrigerate until you leave. Eat with a spoon. If you are worried about spoilage, eat the cheese first, but I haven't ever had a problem. The PB absorbs the oil that comes out of the cheese. The PB jar does not leak. The dense calories make up for the weight of the jar.
