That made life much easier and especially since I don’t seem to own a fine-mesh sieve. I will have to remember to put that gadget on my holiday gift list.

Keto Sugar Free Lemon Curd
- 3 large eggs room temperature
- ⅔ cup powdered low carb sweetener
- ½ cup fresh lemon juice juice of about 2 large lemons
- 1 ½ teaspoon finely grated lemon zest use a Microplane zester to grate fine enough so no straining of curd is needed.
- 4 tablespoon butter room temperature diced
- In a small saucepan (not heated yet), combine sweetener, lemon juice, lemon zest, and whole eggs. Whisk until combined.
- Add the butter and cook over medium-low heat, while stirring continuously with a whisk or wooden spoon, until the first bubble appears and the curd is thick enough to hold marks of the whisk or spoon, about 4-7 minutes.
- Strain with a mesh strainer if needed. Transfer the warm lemon curd to a jar and cover the surface with plastic wrap.
- Refrigerate until cold, then remove the plastic wrap and replace it with a lid. The lemon curd will keep fresh in the refrigerator for about 1 week. Makes just under 2 cups.
