Ingredients
  

  • 3 large egg yolks
  • 1/3 cup fresh lemon juice (about 2 lemons)
  • Zest of 1 lemon
  • 1/2 cup powdered erythritol (or keto sweetener of choice)
  • 1/4 cup unsalted butter, cubed

Instructions
 

Whisk the Base:

  • In a saucepan off the heat, whisk together the egg yolks and powdered erythritol until smooth and slightly pale.

Add Lemon Elements:

  • Stir in the fresh lemon juice and zest. Whisk until fully combined.

Cook Low and Slow:

  • Place over low heat and whisk constantly for 7–10 minutes, until the mixture thickens and coats the back of a spoon. Do not boil.

Finish It Off:

  • Remove from heat. Whisk in the butter cubes until smooth. For the silkiest texture, strain through a fine mesh sieve. Let cool, then store in a sealed jar in the refrigerator.

Notes

  • Store in the fridge up to 7 days
  • Freeze in airtight containers for up to 3 months
  • Use in keto tarts, cheesecakes, pancakes, or enjoy by the spoon!
  • Don’t skip the straining step for a smoother finish
  • For a dairy-free version, substitute butter with coconut oil
