the practice of germinating seeds (e.g., mung beans, sunflower seeds, etc.) to be eaten raw or cooked1)
It can be a way to get fresh vegetarian food or greens in a van.
The usual process is:
a long soak, perhaps overnight, followed by
draining upside down
then rinsing/draining upside down a few times a day until desired growth is reached. A common stopping point is when the grown “tail” gets as long as the seed. This typically takes 2-5 days.
Keeping the jar upside down keeps the sprouts moist but not sitting in moisture.
Dedicated sprouting gear does exist, though mason jars with breathable lids (cheesecloth, screen, etc) works fine. Widemouth jars are easier to clean and remove sprouts from.
