Guidelines in Preparing Vanilla Custard Sauce
1. Use clean, sanitized equipment and follow procedure
2. When combining the egg yolks and sugar, whip the mixture as soon as the sugar is added. Letting the sugar and egg yolks stand together without mixing creates lumps
3. Scald milk before combining with the yolks
4. Slowly beat the hot milk into the beaten eggs and sugar
5. Place bowl with egg mixture in a pan of simmering water and stir constantly to prevent curdling
6. To test for doneness, the mixture lightly coats the back of the spoon
7. Immediately cool the sauce by setting the pan or bowl in ice water. Stir occasionally to cool evenly
8. If the sauce curdles, immediately stir in one (1) to two (2) ounces cold milk, transfer the sauce to a blender, and blend at high speed
