Mix the yolk with mustard, Worcester sauce and pepper. I was not able to find Worcestershire sauce, as I was looking for. Googling, than you can replace. In General, nothing. None of the options did not suit me. I decided that the closest thing would be the sauce Narsharab. It and used.

Pour in beer, mix well.

If you choose to proceed from the fact that the cheese should be well melted. I took cheese and creamy Russian m. d. Zh. 50% of the "Pride of the Empire" and didn't get the completely smooth texture of the sauce, I failed to obtain, though the cheese was soft to the touch.

Bread cut into slices, browned in the toaster. Hot slices spread with butter.
