Wild food forager Paul Tappenden tells us how to identify the best Field Garlic specimens and suggests how to prepare them.
Last year was a poor year for many species, owing to a late frost that killed a lot of blossoms. Even the plants that are normally hardy, and don’t flower until later in the year, seemed to have suffered. One of those, much to my disappointment, was Field Garlic (Allium vineale). However, this year is different. I have already seen some large healthy patches, that show promise of good harvests.
Field garlic, or “Onion Grass,” as it is more commonly known, is a favorite snack of kids all over the world. They love to chew on the deep green hollow stems that deliver a sweet, oniony flavor. A lot of folks use the scallion-like foliage in cooking. However, for me, the prime part of the Field Garlic plant is the bulb, which tastes like a milder, sweeter form of regular garlic.
Field Garlic plants either begin as tiny bulblets, which drop from the flower stalk, or from the underground bulbs sub-dividing. In either case, field garlic tends to grow in tight clusters, that give the appearance of a clump of grass. For about a year, the plants are too small to have worthwhile bulbs. It is only during the second year, when the stems begin to swell and grow tall, that there is a chance that the bulb has fattened up and is ready to harvest. Depending on the location, it could take a few years.
I use parts of the plant in all kinds of dishes. It is fun to use the bulbs whole, like pearl onions. In fact, there are so many ways to use them, that the only restriction is your imagination. My favorite way to prepare them, however, is pickled in a mild, sweet vinegar (my homemade red clover vinegar is ideal for the purpose and turns the bulbs pink).
