Tabasco actually sells little 1/8th ounce tabasco bottles in 6 packs, see their web site. One problem, I've had a couple that leaked when stowed in relatively stable survival kits. Don't know why but tabasco is pretty corrosive stuff.
I've taken to the fast food packets myself. some that haven't been mentioned are KFC honey packets (great for low blood sugar problems in the field). I've also seen lemon juice and margerine in packets (all handy things to have). Salt / Pepper/sugar etc. Great stuff for survival kits or just camping.
