Ingredients

Key Lime Curd Ingredients

  • 5 egg yolks
  • 3/4 cup sugar
  • 2 tsp key lime zest
  • 1/2 cup key lime juice
  • 1/8 tsp salt
  • 4 tbsp butter

Instructions

  1. Combine Ingredients: In a heatproof bowl, whisk together the egg yolks, sugar, key lime zest, key lime juice, and salt until fully blended.
  2. Cook the Mixture: Set the bowl over a double boiler on medium-low heat. Whisk the mixture constantly for about 5 to 7 minutes until it thickens to a custard-like consistency.
  3. Add Butter: Remove the bowl from the heat and stir in the butter until the curd is smooth and glossy.
  4. Cool and Refrigerate: Transfer the curd to a jar or airtight container. Allow it to cool to room temperature before refrigerating for a few hours until it sets and thickens further.

Notes

  • Use freshly squeezed key lime juice and zest for the best flavor.
  • Continually whisking while cooking prevents lumps and curdling.
  • Store refrigerated in an airtight container for up to 1 week.
  • Perfect as a spread, pie filling, or layered in desserts.
