Ingredients

1 cup sugar

1 tablespoon finely grated lemon zest, plus 1/4 cup fresh lemon juice

8 large egg yolks (egg whites reserved for another use)

1/4 teaspoon coarse salt

1 1/4 sticks unsalted butter (10 tablespoons), cut into 1/2-inch pieces

1 cup raspberries

Preparation

  1. In a medium saucepan, off heat, whisk together sugar, zest, and egg yolks; whisk in lemon juice and salt.

2)Add butter and place pan over medium-high heat. Cook, whisking constantly, until butter has melted, mixture is thick enough to coat the back of a spoon, and small bubbles form around the edge of pan, about 5 minutes (do not boil).

  1. Remove pan from heat while continuing to whisk. Pour curd through a fine-mesh sieve into a glass bowl. Press plastic wrap against the surface of curd and refrigerate until cool. (To store, refrigerate in an airtight container, up to 2 weeks.)

4)In a blender, puree 1 cup raspberries. Strain through a fine-mesh sieve into a bowl, discarding solids. Fold raspberry puree into cooled curd.
