Penne with Spinach Cream

Tried once a while ago, cannot remember details, but it still sounds delicious. Posting to remind myself.

Penne with Spinach Cream

2 tbsp unsalted butter
6 cloves garlic
14 oz fresh spinach (or frozen. i usually have frozen.)
1 1/4 cup heavy cream
pinch of fresh ground nutmeg (yeah i dont have that..)
1 tsp lemon juice
1 lb penne (cook according to package directions)
2 tbsp olive oil
1 to 1 1/2 cups parmesan, grated

Cook garlic and spinach in butter. Squeeze dry, and reduce the resulting liquid by half. Return spinach to the pan. Add cream. Reduce by half. Pulse in a food processor (or likely, for me, use chopped frozen spinach and mince garlic to begin with). Adjust seasonings with s&p, nutmeg, lemon juice. Toss with hot pasta, oil, and parmesan.
