Description

In my family, this mustard sauce is as essential as the ham on the holiday table. It takes no time to whisk together, and it is so nice to have on hand for leftover ham sandwiches. 


Ingredients

  • 1/2 cup sugar
  • 1/4 cup white wine vinegar
  • 4 tablespoons dry mustard
  • 4 egg yolks
  • 1 teaspoon kosher salt
  • 1 cup heavy cream

Instructions

  1. Place a strainer over a medium-sized bowl (able to hold about 2 cups of liquid). Combine all ingredients in a saucepan. Bring to a boil while monitoring closely and stirring often. As soon as the mixture comes to boil, pour it through the strainer into the bowl. Let cool, then cover with plastic wrap and place in the fridge.
