Directions
Make the sauce
Mix the arrowroot with the milk, nutmeg, and lemon peel in a bowl until smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrowroot
- Thickens the milk and butter into a smooth, glossy sauce as it is gently heated.
- Butter
- Adds richness and a silky mouthfeel that carries the flavorings.
- Milk
- Provides the liquid that the arrowroot thickens into the sauce base.
- Cold butter
- Melted in at the end, it adds gloss and a fresh, rounded richness.
The step that matters
Heating the arrowroot mixture. Arrowroot thickens when heated but can break down or turn thin and gluey if overheated or boiled too long. Keeping the heat low and stirring until blended gives a smooth, stable sauce.
Swap the arrowroot
