An epicure's joy, cipollinis ("little onions" in Italian) are popular with cooks for their small size and mild, sweet flavor. They are traditionally served whole, pickled or used in kebabs, but we also love them roasted or fresh in salads. 'Borettana' onions are about 2"–3" wide, 1" deep and flat both top and bottom. The smooth, thin skin covering the onion is a beautiful bronze. Stores well.

Special Care: Keep growing area weed-free. Onion size can decrease 4% per day if competing with weeds—that's 50% in two weeks. If bulb pushes itself out of the ground, you may cover it lightly with straw, but not soil, as soil will prevent the onion bulb from forming properly.

Harvesting: When onion tops have fallen over and turned yellow or brown, they are ready for harvest. Harvest in the morning, lifting onions with a garden fork. Dry them in the garden in the sun for 2 to 3 days, lightly covering the bulbs with straw, or the tops of other onions to prevent sunscald. Cure onions for 3 to 7 days in a dry area with good air circulation. Once dry, cut the roots to ¼", and the greens to 1" to create a seal, preventing decay.
