To cook artichokes, you first have to trim down the spiky edges using kitchen scissors, and chop off a bit of the bottom so that they can stand upright. Put them in a pot of boiling water, approximately 1 inch deep, cover, and steam on medium heat for approximately 25-35 minutes (depending on their size), until the bottom is soft. Then sprinkle with freshly squeezed lemon juice.
The bottom of each leaf holds the edible part.... dip it in a vinaigrette and then scoop out the soft part with your teeth.
Mmmmmm, one leaf down, 99 to go!
