Penne with Roasted Shallots and Porcini Mushroom Glaze

The pasta salad is particularly nice for company because fresh porcini mushrooms, available only in the fall, are special. The wait for them is worth it. Use cremini, shiitake, or a combination of the two at other times. If you are serving this for a special occasion, roast tenderloin, with or without a peppercorn crust, is the ideal accompaniment. Because of the cream in the mushroom glaze, this pasta, special as it is, does not keep.
