  1. Preheat oven to 325 degrees F.

  11. Pour mixture through a strainer to get out all the little bits of gelatin and egg that did not incorporate.
  12. Add coconut oil to the lemon mixture and whisk until it is fully emulsified.
  13. Pour lemon filling into your silicone mold on top of the crust for the lemon tarts. If making the bars just pour the lemon filling into your Pyrex dish.
