Method
Prepare the Tart Crust
- In a mixing bowl, combine flour and powdered sugar. Add cold butter and mix until crumbly.
- Stir in egg yolk and add cold water, one tablespoon at a time, until dough forms.
- Press the dough into a 9-inch tart pan and refrigerate for 30 minutes.
Make the Filling
- In a saucepan, combine chopped rhubarb, hibiscus tea, sugar, cornstarch, vanilla extract, and salt.
- Cook over medium heat until rhubarb is tender and mixture thickens, about 10-15 minutes.
Assemble and Bake
- Preheat the oven to 350°F (175°C).
- Pour the filling into the prepared tart crust and spread evenly.
- Bake for 25-30 minutes until the crust is golden and the filling is bubbly.
- Allow to cool before serving.
Notes
