Ingredients

Scale
  • 1 ½ cups (150g) graham cracker crumbs (preferably honey-flavored)
  • 6 tablespoons (85g) unsalted butter, melted
  • 2 tablespoons granulated sugar
  • ½ teaspoon ground cinnamon (optional)
  • 1 ½ cups (225g) fresh rhubarb stalks, chopped (frozen can be used, thawed and drained)
  • ¾ cup (150g) granulated sugar
  • 3 large eggs, room temperature
  • 2 large egg yolks
  • 6 tablespoons (85g) unsalted butter, cubed
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon vanilla extract (optional for curd)
  • 4 large egg whites, room temperature
  • ¾ cup (150g) granulated sugar
  • ¼ teaspoon cream of tartar (optional)
  • 1 teaspoon vanilla extract (for meringue)

Instructions

  1. Preheat oven to 350°F (175°C). Crush graham crackers finely using a food processor or place in a zip-top bag and crush with a rolling pin.
  2. In a mixing bowl, combine graham cracker crumbs, sugar, and cinnamon if using. Stir in melted butter until mixture resembles wet sand.
  3. Press the mixture evenly into the bottom and up the sides of a 9-inch tart pan with removable bottom, about ¼ inch thick.
  4. Bake crust for 10 minutes until fragrant and set. Remove and cool completely on a wire rack.
  5. Roughly chop rhubarb. In a medium saucepan, combine rhubarb, sugar, and lemon juice. Cook over medium heat, stirring occasionally, until rhubarb softens (8-10 minutes).
  6. Remove from heat and strain through a fine-mesh sieve, pressing to extract juice. Discard solids.
  7. In a heatproof bowl, whisk eggs and egg yolks. Gradually whisk in rhubarb juice mixture.
  8. Return mixture to saucepan and cook over low heat, stirring constantly, until thickened and reaches about 170°F (77°C), coating the back of a spoon.
  9. Remove from heat and whisk in cold cubed butter and vanilla extract until smooth.
  10. Pour curd into a bowl, cover with plastic wrap pressed onto surface, and chill at least 2 hours until set and cool.
  11. For Swiss meringue, combine egg whites and sugar in a heatproof bowl over simmering water. Whisk constantly until sugar dissolves and mixture is warm (~160°F or 71°C).
  12. Remove from heat and whip with mixer on high until stiff, glossy peaks form. Beat in cream of tartar and vanilla extract.
  13. Spoon chilled rhubarb curd into cooled crust and spread evenly.
  14. Pipe or spoon Swiss meringue on top, creating peaks or swirls as desired.
  15. Brown meringue with a kitchen torch or under broiler for 1-2 minutes, watching carefully to avoid burning.
  16. Let tart rest at room temperature for 10-15 minutes before slicing and serving.

Notes

Use fresh, high-quality eggs for best texture. For gluten-free crust, substitute graham cracker crumbs with almond flour or gluten-free crumbs. For dairy-free, use plant-based butter substitutes. Keep heat low when cooking curd to avoid scrambling eggs. Fully dissolve sugar in meringue step to prevent deflation. Brown meringue carefully to avoid burning. Store tart covered in refrigerator up to 3 days; reheat gently in oven to refresh meringue.
