Here is how to cook dandelions.
Wash and clean a bunch or two of dandelions.
Bring to a boil a quart of filtered water.
Put the greens into the boiling water.
Boil for 5 to 10 minutes, until look and feel tender.
Take the greens out the pot with a slatted spoon and plunge immediately into a bowl with plenty of cold water to cover.
Take a bunch of the leaves with your hand , make a ball and squeeze with both hands to remove the extra water and some of the bitterness.
Put on a cutting board and chop the greens up in small pieces.
You can eat the greens the way are, by seasoning them with lemon juice and sea salt, Or
Saute olive oil and garlic until golden in color, then add the blanched greens and cook for 5 to 10 minutes, adding little water if needed, near the end, add soy sauce or sea salt. Continue to cook for a minute and serve.
