Made with fresh lemons, this creamy sauce is rich and custard-like with a good balance of sweet-tart flavor. It’s everything you love in a lemon curd but with a thinner, pourable consistency.
Place the eggs in a medium size saucepan and whisk them to break them up. Add sugar and salt and whisk until combined. Stir in the lemon juice.
Heat the mixture over medium heat until it just barely comes to a gentle simmer (don't let it come to a boil). Reduce the heat to medium-low. Cook, stirring continually for 12 to 15 minutes or until it is thick enough to coat the back of a spoon. Stir in the butter until completely melted.
Pour the sauce through a fine metal strainer into a bowl. Discard any lumps that get left in the strainer.
Press plastic wrap over the top of the sauce and refrigerate until chilled. The sauce will thicken slightly when cool.
This will make about 2 cups of sauce. Store in a covered container in the refrigerator for one week.
