Bring water and Demerara sugar to a boil in a 2-quart heavy saucepan

Whisk together yolks and vanilla in a large bowl, then add hot cream mixture in a stream, whisking. Pour
custard through a fine-mesh
sieve into a 1-quart glass measure. Skim off any foam with a spoon.
Divide custard among ramekins. Arrange ramekins in a small roasting pan and bake in a hot water bath,
uncovered, until custards are set around edges but still tremble slightly in centers, about 40 minutes.
Transfer ramekins to a rack with tongs and cool to warm or room temperature. Pots de crème will continü
to set as they cool.
Cooks' note:
# Custard can be made, but not baked, 1 day ahead and chilled, covered, in glass measure.

These pots de crème won raves from our food editors for their wonderful butterscotch flavor and creamy
texture. The combination of muscovado and Demerara sugars gives the custard its deep flavor.
