1 cup milk
1 roasted garlic clove, smashed [optional]
1 lb monterey jack cheese, coarsely grated (don't buy the pre-grated cheese)
2 tablespoons flour

Heat the milk [and the garlic] in a saucepan over medium-low heat until
simmering, 2 to 3 minutes.  Toss the cheese and flour together in a
bowl until the shreds are nicely floured.  Whisk the cheese mixture
into the milk a handful at a time, waiting until each handful melts
before adding more. Whisk until cheese is completely melted and
mixture is smooth and velvety.
