- 1 cup sugar
- 1/2 cup lemon juice
- 3 eggs plus 1 egg yolk
- 4 tablespoons unsalted butter, cut into cubes and softened
- 1 teaspoon lemon zest
- 1/8 teaspoon fine sea salt
Nestle the bowl into the pot and reduce the heat to maintain a simmer in the water below. Slowly and constantly whisk egg mixture, occasionally scraping down the sides, until very thick, 8 to 10 minutes. Strain mixture through a fine sieve, discarding any solids and transfer to a clean, heat-safe bowl. Stir in butter until well combined and then stir in zest and salt.
Set aside to let cool to room temperature and then cover the surface with plastic wrap and chill until cold, about 4 hours.
