Pick smaller bulbs (under 3 in in diameter) that weigh heavier than they seem. Look for smooth skin and firm green leaves.
Remove the leaves (they can be used in the same way as kale), trim the stems, scrub the bulb clean, pat dry and wrap in a plastic bag. This way, it will keep in the crisper for up to 2 weeks.
