Microgreens are edible seedlings from various vegetable and herb plants that take around 10-21 days to harvest, depending on the variety that is grown. Microgreens gained popularity in the 1980s in San Francisco, California, and are known for their savory and pungent taste profile. In the past, microgreens were used only as a garnish, but today many chefs are using microgreens as a basic ingredient in culinary dishes around the world.
