Ingredients

Method

Combine zest, juice, sugar and eggs in a heatproof bowl, and beat well. Add butter, and place over a saucepan full of simmering water. Cook, stirring constantly with a rubber spatula or wooden spoon, until mixture thickens into curd, about 5 minutes. Strain into a bowl, and press plastic wrap onto surface to keep skin from forming. Refrigerate until cool, at least 1½ hours.
