Cream of Cauliflower Soup w/ Ginger

How do you "core" this thing???

• 2 leeks, roots trimmed, including 2 inches of green
• 2 tbsp olive oil
• 2 tbsp butter
• 1 celery rib, with extra leaves, coarsely chopped
• 2 tbsp finely minced garlic (about 4 cloves)
• 2 tsp curry powder
• 2 tsp ground ginger
• 6 cups chicken broth
• juice of half a lemon
• 1 head cauliflower, cored & broken into florets. Here we go - anyone know how to core a cauliflower? I asked around and the answer was no. So I just cut the bitch.
• 1 cup half & half
• salt & pepper
• crystallized ginger

Cut leeks in half, lengthwise. Wash to remove dirt. Pat dry & thinly slice crosswise.

Heat the oil with the butter in a heavy pot over low heat. Wilt the leeks & celery with leaves until softened, 10 minutes; add garlic during the last 5 minutes.

Stir in the curry powder & ginger and cook over very low heat to permeate the vegetables, 1 minute. Add the broth, lemon juice & cauliflower florets. Raise the heat to high & bring to a boil; reduce the heat & simmer, partially covered, until the cauliflower is very tender, 15 minutes. Cool slightly.

Puree in a food processor until very smooth, adding half & half thru the feed tube. Add extra broth for desired consistency. Salt & pepper to taste.

Sprinkle with crystallized ginger, sliced leeks or florets.
