A Fine Day to Cook

The sky is gray, the air damp; clouds loom.  It's a day to stay inside and cook.

After the silly recipes of the past few days, here's one that sounds like a project worth investing time in.  (I have no Tilsit on hand, so I'll probably substitute a pungent Gouda.)

I imagine serving this with roasted tomato soup, and perhaps a cucumber salad on the side.  Lovely little dinner on an almost-fall night.
