Pro Tips for Success:

  • Use fresh lemons for the best flavor — bottled juice won’t give you the same zesty punch.

  • Add a pinch of salt to the crust to bring out the buttery flavor even more.

  • Swap butter for ghee or coconut oil if you’re dairy-free or paleo.

  • Dust with powdered monk fruit after baking for a pretty finish without the sugar.
