Swiss chard with pasta and cream

1 lb swiss chard, yielding 2 cups of chopped ribs
half a stick butter
3/4 to 1 cup heavy cream
Enough dry pasta to make about one quart of cooked pasta
Salt and pepper

1 Separate the ribs from the greens in the manner described here. Cut the ribs into 1/2-inch to 1-inch pieces. Blanch the ribs in lightly salted boiling water for 3 minutes.

2 Melt butter in a saucepan on medium heat. Add the drained, blanched ribs and simmer for 4 minutes. Add heavy cream and cook until cream reduces by two-thirds.

3 While the cream is reducing, cook up your pasta according to the pasta's package directions.

4 Mix creamed chard with pasta. Season lightly with salt and freshly ground pepper.
