Dan McKean, the owner of True Leaf Microgreens: "Microgreens are vegetable or herb seeds that are grown to the first set of leaves, the cotyledon leaves, rather than being allowed to grow into seedlings for planting in the garden."
The second leaf that develops in these tiny plants is called the true leaf and he says that's the inspiration for the name of the business.
It is at this point in their growth when they are at their most nutrient-dense stage, if you look into the research, microgreens are anywhere between four to 40 times more nutrient-dense than their adult counterpart.
Needless to say, it is also when they have a big flavour impact. Dan says that microgreens immediately elevate the presentation of any dish or make a solid component in a meal all on their own.
