Sunchoke Gratin

Directions

1. 1
   Preheat oven to 375 degrees F. Reduce cream in a heavy saucepan over medium heat by about 1/3. Slice sunchokes very thin with a mandolin or in a food processor.
2. 2
   Butter a small casserole or 8 inch square baking dish. Arrange a thin layer of sunchokes. Top with a few spoonfuls of cream, a few spoons of both cheeses, salt and pepper. Continue layering until you have used all the sunchokes. The top layer should be cheese.
3. 3
   Bake 45 minutes or until tender when pierced with a knife. Run under the broiler for a few minutes to brown top, if desired.
