Erm… gonna have to disagree with this. You can’t make vinegar by dumping rotten juice in a barrel. The only somewhat realistic method of quick-producing vinegar involves bacterial cultures and still takes at least 20 hours, which is more than a little impractical with DDA’s current “watch the pot boil” style of cooking.
Also it’s not like vinegar is the sole ingredient in anything: I assume you want it for batteries but I may be wrong. Why not bottle acid rain instead? Vinegar is a luxury, strange as that sounds, and crafting it just wouldn’t make sense.[/quote]
Fermentation vats (and yeast-culturing flasks) actually are an exception to pot-watching: they’re programmed to check times, and IIRC function independently of the reality bubble. If you work up a recipe for aging X into vinegar, the vats could probably handle it.
