How do you get bread to mold on purpose?!
Answers: Moisture and warmth is what makes bread mold grow. Most bread is moist already, but you can help it by sprinkling a little bit of water in the bread bag (not a lot, or you'll just make a soggy mess), then close tightly and leave it in a warm place in your house.
Rub the slices on a counter and leave it in a dark humid place for a while lol.
yep leave it moist and in the open air
Leave it somewhere warm for a few days ..
