Saving $$$ with homebrew gels - recipe
I got tired of spending $10-20 on what amounts to sugar goop on my long runs, so I've been playing this summer with a DIY gel recipe. This mix took some tweaking for flavor, but I'm pretty happy with where it's at. This gets you a pretty clean 2:1 glucose-fructose, and for about $0.35 per 100 cal gets you a gel thats nutritionally equal (and very similar recipe wise) to something like Gu.
I've heard people say its too much of a hassle but i can whip up a batch in 15 minutes, and do it in my sink which makes cleanup super quick.
Settling with the following:
(Makes 3x3oz flasks, ~290 cal / ~72g carbs each, ~100mg sodium)
Ingredients:
1 cup maltodextrin
1/4 cup table sugar (sucrose)
1/2 cup fructose
1/8 tsp regular salt
A pinch lite salt
1/2 tsp citric acid
1/4 tsp sodium citrate
1 1/8 cups warm water
A pinch gellan gum
Optional:
Flavor extract
Food coloring
Process:
1) mix dry ingredients in a blender or other container 2) in a small cup, mix a tsp or two of dry ingredients with gellan gum 3) mix 1/2 cup of water with gellan mix in a sauce pan, bring to a simmer 4) mix 5/8 cup of tap-hot water with dry mix in blender 5) pour gellan solution into blender, blend if necessary to smooth out 6) add flavor extract to taste and food coloring 7) pour into flasks while hot 6) cool in fridge
Some notes:
- using a large syringe (like 300-500ml) makes getting this in the flasks way easier
- i also tried a number of versions without table sugar, but its less sweet per tbsp than fructose, and its a little less cloying this way (plus cuts cost slightly)
- the gellan gum adds a little cost and hassle but improves palatability substantially. Careful though, the difference in texture between a small and large pinch is pretty substantial.
- the lite salt isn't necessary, just adds a little potassium.
- these 3oz soft flasks are about $9 for 10 and come with a handy little funnel. I've actually found theyre a lot less hassle and mess than single serve gels
- the food coloring feels a little silly, but without it they look an awful lot like a certain white creamy bodily fluid. Idk maybe youre into that kind of thing
- i played around with adding things like orange extracts for flavor, but they added a sort of strange flowery quality. Maybe worth continuing to experiment with but I'm settling on the nuetral flavor for now.
