- 3 large eggs
- 2/3 cup sugar
- 2 teaspoons finely grated Meyer or regular lemon zest
- 1/2 cup fresh Meyer or regular lemon juice
- 2 tablespoons unsalted butter, cut into pieces
- 1 1/2 cups chilled heavy cream
- 6 graham crackers, crumbled
- Flaky sea salt (such as Maldon)
- Cook eggs, sugar, and lemon juice in a medium saucepan over medium heat, whisking constantly, until thickened (mixture should coat a spoon), 8–10 minutes.
- Transfer mixture to a blender and blend on low speed, gradually adding butter, until mixture is smooth (you're not trying to aerate the mixture, so keep blender on low speed). Transfer lemon curd to a medium bowl, cover, and chill at least 2 hours.
- Just before serving, whisk cream into lemon curd. Layer lemon cream and graham crackers in small glasses or bowls, finishing with graham crackers. Top with lemon zest and sea salt.
- DO AHEAD: Lemon curd can be made 1 week ahead. Keep chilled.
