  • 3 large eggs
  • 3/4 cup granulated sugar
  • 1/4 cup key lime juice 8-10 key limes
  • 1 tablespoon key lime zest
  • 1/4 teaspoon kosher salt
  • 4 tablespoon unsalted butter


  • In a small pot, off the burner, whisk together eggs and sugar until well blended.
  • Whisk in key lime juice, zest, and salt.
  • Place the pot on a burn on medium-low heat and stir fast and constantly with wooden spoon until mixture is warmed through.
  • Add the butter a tablespoon at a time until melted and curd becomes smooth.
  • Continue stirring constantly until curd thickens and looks almost creamy.
  • The curd is done once it coats the back of a spoon.
  • Optional Step: Strain curd through a cheesecloth or fine mesh sieve into a medium bowl to remove zest pieces and any clumps.
  • Tightly seal the bowl with a cover or cling wrap and place in the fridge until completely cooled.
  • Once cooled, spoon about a tablespoon or a little less into the holes you cored out in the cupcakes.
