Directions:

1. Preheat broiler.

3. Melt remaining tablespoon butter in a 1-quart heavy saucepan over low heat, then add flour and cook, whisking constantly, 1 minute. Add beer and milk in a stream, whisking, then whisk in mustard, pepper, and cheese. Bring to a simmer over moderately low heat, whisking, then simmer, whisking, until smooth, about 2 minutes.
4. Remove from heat and immediately whisk in yolk. Serve cheese sauce on toast.
