Tassel Hyacinth is used in regional Italian cooking and in Greece. In Italy, they are most commonly used in the Puglia region (Apulia) and locally they are called "lampascioni" or "lampasciuni" or "lamponi". Do not confuse them with cipolline onions.

2 Tablespoons extra virgin olive oil
6 cloves of garlic
18 black olives
1 Tablespoon fresh, chopped rosemary
3.5 Tablespoons balsamic vinegar
Kosher Salt
6 lampagioni/tassel hyacinth bulbs
Prior to cooking the tassel hyacinth, the outer leaves must be removed and the bulbs should soak in cool water, that is changed occasionally, so that some of
their bitterness is lost.

In food process combine 6 peeled bulbs of garlic, oil olive, rosemary, 1 tablespoon salt, 3 lampagioni bulbs, black olives, and balsamic vinegar. Process until garlic, rosemary, and lampagioni are finely minced.
Evenly coat top and sides of the lamb with mixture. Marinate at room temperature for 1 hour.
