What each ingredient does
- Egg
- Binds and thickens the sauce as it heats.
- Brown sugar
- Adds sweetness and a deep caramel-like flavor.
- Molasses
- Adds dark color, moisture, and a rich, slightly bitter sweetness.
- Vinegar
- Adds acidity that brightens the sweet, rich flavors.
The step that matters
Stirring while bringing to a boil. Egg proteins can scramble or stick to the pan if the mixture heats unevenly. Constant stirring keeps heat distributed so the sauce thickens smoothly.
