I've been musing on the idea of incorporating more "liquid calories" into my hiking diet. I've read a few threads about what mixes people use/make, and I'll be making my own when I figure out exactly what I want. This is for 12+ hour days of hiking/running. I would have two types for two uses:
1. as an on the trail snack replacement. I usually have a mostly nut gorp and every 4-5 miles stop and have a handful with water. I would replace this with something more carb based, with some protein. It seems the easiest thing to do is have two bottles, one for water, and one for a concentrated mix of this, and take a slurp of it every now and then. So I envision using an entire bottle per day (I'm thinking 20oz poland spring bottle).
2. With dinner "recovery" mix, more proteins and fats than the previous. I would be using much less of this per day.
So the two issues I can think of are storing the powder, and mixing it properly. Pouring into a small mouthed bottle like a platy or poland spring would also be troublesome. I know most people just use ziploc bags, but I think something better could be found. Some ideas that I have had, that may help someone, or maybe someone can help me:
1. fill a bottle full of hiking powder for each day. Leave a bit of space for water, pour water in the night before, and try to mix, letting it set overnight might help. But likely it would be impossible to get a good consistency with this method. You would also have a few extra bottles, but they are pretty light and could serve a later purpose.
2. for storing a large amount of powder that you want to use incrementally, like my use with dinner. I recall pastry bags (for squeezing icing on cakes and things) having interchangeable tips, and maybe you could find one with a secure closing. The bag could be filled and tied off, and then you could pour powder out the tip.
3. for making a drink, could make "tea bags" of the powder, and then fish them back out when done, of find something that dissolves and just toss it into the bottle.
Any of the chefs on here know more about pastry bags?
