I learned about using drinking straws to package up small amounts of powders, either here on Backpackinglight, or maybe on some blog somewhere. You cut off a small section of straw, pinch another segment and fold it back, then slide the small section over it as a sleeve to maintain the pinch. Then pack however long a segment you want with spice, and repeat on the other end to seal it. I have six of these lined up in a small zip-lock bag, with curry, italian seasoning, cinnamon, vanilla powder, garlic powder, and chili powder. Toss in a few packets of salt and pepper from a take-away restaurant, and I have a tiny spice kit that doesn't weigh much, and fits in my cook-kit. I haven't used it much, because I make my own meals and season them at home, and I was almost ready to ditch it from the cook-kit, until I got one meal last time that didn't have enough, then I was glad I had it! I labled each one with a DYMO Labeler, and seal the slide-on ends with scotch tape.
The other food correction thing I have done lately is carry a snack bag with extra mashed potato flakes. If I got too much water in the meal, dump a little in and stir it around = perfect consistency. Have to do that again!
