SCALLIONS AND LEEKS
Trim the entire white portion off the bottom of a leek or scallion stalk, then place it root-side-down in a jar or glass holding an inch of water. If the stalk outgrows the jar, move it to a larger one. New growth will be harvestable in a couple of weeks.
ROMAINE LETTUCE
Cut 3 inches off the bottom of a head of romaine lettuce, then remove its outermost leaves. Place the 3-inch "heart" in a shallow container to which you've added one-half inch of water. Within a week, a sprout will emerge from its center. As it grows, it's normal for some of the heart's outer leaves to turn brown. Remove them. When the center growth is large enough for a salad (or sandwich), trim it off and enjoy - then wait for more to grow.
