I'm going camping and like the idea of mixing my dry ingrediants in a zip loc at home and then adding egg and water at the campsite to make pancakes (milk spoils and I won't have access to a freezer right before camping so I can't do the freeze and thaw trick). Prob is my normal recipe calls for milk instead of water. Can I just substitute and it will be a little less good (in which case do I adjust any of the other ingrediants)? Or should I search out powdered milk? Or should I just give in and buy one of the prepackaged mixes that does not call for milk? Or has someone used soymilk successfully? They sell small cartons of soy milk that don't have to be refrigerated.
