Make your own homemade Key Lime Curd in less than 20 minutes!



1/2 cup granulated sugar
1/4 cup cold water
3 tablespoons cornstarch
1/4 cup key lime juice
2 teaspoons of lime zest


  1. In a saucepan, mix together the sugar, water and cornstarch.
  2. Bring it to a boil on low-medium heat and whisk constantly. This mixture needs to get fairly thick – almost like a thick pudding consistency.
  3. When the mixture thickens, reduce your heat to low and stir/whisk for another minute.
  4. Remove the mixture from the heat, place in a non-metallic bowl and add key lime juice and zest.
  5. Allow your key lime curd to cool and thicken at room temperature.
  6. Store in your fridge for up to a three days.
