Leek

Allium ampeloprasum

vegetable · prebiotic

Long, flat, sheathing leaves whose base forms a white shaft, the most prized part; the green, more fibrous, is eaten too. Its fructans feed bifidobacteria.

Origin

Eastern Mediterranean

Season (United States)

September to April · grows in your region

Preparation

The green is edible and richer in fibers than the white. Split it lengthwise and rinse between the leaves: that is where the soil hides. Chop or crush it, then wait ten minutes before cooking: that is how long its sulfur compounds take to form.

Molecules
