Ingredients
  

  • ½ cup fresh lemon juice
  • cup granulated sugar for lemon curd
  • ¼ cup granulated sugar for whipped cream
  • cup water
  • 3 tablespoons cornstarch
  • 1 pinch ground turmeric optional, for color
  • 1 cup cold whipping cream

Instructions
 

  • In a small saucepan, whisk together lemon juice, water, ⅔ cup sugar, cornstarch, and turmeric.
  • Place over medium heat and stir continuously until the mixture thickens to a pudding-like consistency, about 3–4 minutes.
  • Remove from heat and let the lemon curd cool completely before using.
  • In a chilled mixing bowl, whip the cold cream with the remaining ¼ cup of sugar until soft peaks form. Do not overwhip.
  • Gently fold the cooled lemon curd into the whipped cream in batches using a spatula. Mix just until combined and airy.
  • Spoon the mousse into dessert glasses or jars. Chill in the refrigerator for at least 1 hour before serving.

Notes

For added flair, top with lemon zest, fresh berries, or mint leaves. To add crunch, layer with graham cracker crumbs or vanilla wafers. This mousse is also lovely served parfait-style with alternating layers of yogurt or extra cream. For a dairy-free version, use coconut cream and plant-based whipping cream.
