I started making my own hot sauce (for private distribution only) this past fall, and now I've got several empty bottles (standard 5-oz hot sauce style) that used to contain it. Can I, if I clean and sterilize these bottles, use them again for another batch of sauce? I'm assuming that the caps and reducers (being plastic) probably can't be effectively re-sterilized, but the bottles are glass, so a good few minutes' boiling after they've been hand-washed and run through the dishwasher to remove residue ought to do it - or am I wrong?
