- 6 Tbsp unsalted butter softened
- 1 C sugar
- 2 large eggs
- 2 large egg yolks
- ⅔ C fresh lemon juice (about 2 large lemons)
- 1 tsp. lemon zest
- In a large bowl beat the butter and sugar with an electric mixer for about 1 minute. Slowly add the eggs and yolks and continue to beat for another minute. Mix in the lemon juice, it will look curdled.
- In a heavy saucepan cook the mixture over low heat until it looks smooth - until it no longer looks curdled. Increase the heat to medium and cook, whisking constantly - do not let it boil! Keep whisking until the mixture thickens, it should leave a path on the back of the spoon. - about 10-15 minutes.
- Remove from heat and stir in the lemon zest. Transfer to a storage container (mason jar or tupperwear). Press a piece of plastic wrap or wax paper over the top to keep a skin from forming on the top of the curd. Cover tightly and store in the refridgerator for up to 1 week.
