Now thats what I'm talking about...I use buttermilk at home for just that reason...have even used the vinager trick to make my own in a pinch. I use powdered milk for my own little breakfast shake concoction on camping trips and it never occured to me to look for powdered buttermilk. TY TY
You brought up somthing thats been missing from my little list of long shelf life powerful basics...Acid
Vinagers and Citrus juices are fine at home but, as with fats, they are messy after 2-3 weeks on the trail (one of my goals is to have less items that need a double bagging of ziplocks). I imagine there are pure powdered forms of Citrus, I wonder what other rehydratable acid's there are out there...time to hit google
