In reply to Tall Clare:
didn't know what it was so had to look it up resulting in:
The heads can be roasted whole and the creamy cooked garlic is delicious spread on toast or mixed with butter and used on vegetables or in baked potatoes. The flavour is strong, but smooth and not at all bitter.
While the stalks are fresh and green they can be cooked like leeks or finely sliced and used to make soup, omelettes or garnish salads.
