It's relatively simple arbor - we took a recipe from a wild foods cookbook.
Gather a bucket/big bag full of leaves and stems (the bulbs can go in if you like a very strong garlic flavour - we didn't bother on this occasion), wash, chop and cook in stock or water with two or three of your favourite herbs (we used basil, thyme and oregano!!) and a couple of bay leaves, plus some cloves in one of those tea balls, to make it easy to fish them out.
Once cooked (maybe 15 minutes or so) we removed the cloves and bayleaf and blended half of the soup with salt and black pepper and mixed the gloop back in.
There's a lot of soup from a bucket full of garlic leaves; it could serve about 6-8.
Served with a sprinkling of our "parme sham" - mixed up yeast flakes, ground almonds and salt.
When we do it again, we'll going to add a couple of well-chopped potatoes as the recipe turned out a little thin for my taste, more like an onion soup consistency. Still delicious though. The recipe called for an egg or two swirled into it but who needs eggs.
Here's a good few wild garlic recipes.
Wild garlic smells stronger than cultivated garlic when raw but is not as strong as it when cooked, so adjust usage accordingly. Some wild garlics are stronger than others, so chew on a leaf first: gorgeous.
