Set bowl over a saucepan of simmering water and begin whisking the mixture continuously, until thickened and smooth. This will take about five minutes.

This would make an excellent topping on any sweet breakfast food: scones, granola, English muffins, cheese blintzes or French toast. It will keep in the refrigerator for up to five days.
