Notes
Melt low & slow: Keep the heat on medium-low to prevent the dairy from separating and to get that silky-smooth texture.
Whisk constantly: This helps avoid lumps and keeps the sauce creamy and cohesive.
Make it ahead: The flavor deepens as it sits, making it even better the next day.
Double the batch: This sauce goes fast—great to have extra for meal prep or leftovers.
