Allium sativum
Garlic is the most pungent common allium, with a sharp heat that mellows dramatically with age or heat. Its early-season scapes are also an important Northeast market ingredient.1
An intact garlic clove is comparatively quiet. Crushing it brings enzymes and sulfur-containing precursors together, producing thiosulfinates responsible for much of the familiar pungent aroma.2
Garlic originated in central Asia and has been cultivated for roughly 5,000 years. It is usually propagated from cloves because it rarely produces true seed.3
“Elephant garlic” is a misleading name: it belongs with the leeks and is not a true garlic. In Maine, hardneck garlic is generally the dependable type; its flower stalk is the scape, and the small structures in its flower head are often bulbils—little clonal propagules—rather than seeds.3
A garlic clove is a single swollen storage leaf wrapped around a young shoot, rather than a miniature multilayered onion. It contains much less water than an onion scale and a higher concentration of fructose-based carbohydrates, helping account for garlic’s density and ready browning.4
