1-2lbs (0.5-1 kg)Fresh rhubarb- enough to cover the tart
Slivered Almonds - Optional
Instructions
Make the Crust
In the bowl of a stand mixer, add softened butter and sugar. Beat on medium low setting until incorporated and smooth.
Add egg and continue beating on medium/low setting until incorporated.
With mixer running on low, add flour, salt and continue beating slowly until you get a grainy mixture that comes together when you press it between your fingers .
Place the dough mixture into a 9-inch round tart pan (the kind with the removable bottom). With your fingers, press the mixture down and up the sides until you have full coverage. You can use the bottom of a measuring cup to help you get a nice and flat bottom and even edges.
Place tart pan in fridge for 30 minutes while you make the frangipane mixture. You can also cool in the fridge for up to 2 days, covered well.
Make Frangipane
Using the same stand mixer bowl (you don't need to clean it! The frangipane ingredients are similar), add softened butter, sugar and beat on medium low until you have a smooth consistency.
Add eggs, one at a time, while you continue to beat on low. Add extracts. Continue beating on low. Use spatula to loosen any batter stuck to the sides of the bowl.
While mixer is running on low, add the almond meal, all purpose flour and salt. Continue to mix until you have a smooth batter-like mixture.
Assemble and bake tart
Pre-heat oven to 350F (176C) with rack in the middle.
Remove tart pan from fridge. Tart crust should be cool and hard to the touch. With the tines of a fork, poke a few holes on the base. This helps the crust stay nice and low and not puff up too much.
With a spoon or offset spatula, spread the frangipane mixture evenly in the pan.
Add rhubarb slices on top of the frangipane. Design doesn't matter. You can be as creative as you like. As long you end up with 1 layer of rhubarb and cover the entire surface of the frangipane. You can add sliced almonds around the edge of the tart to hide any uneven rhubarb cuts. This is optional.
Bake for 40-45 minutes. Check on the tart around 30 minutes. If you feel like it may be browning too quickly, then drop the temperature to 325F (162C). Every oven is different so trust your gut.
Cool the tart for at least 30 minutes before cutting into it so that the frangipane can set. Use a sharp knife as it can get tricky to slice through the rhubarb. Tart can be served warm or cold.
Optional: you can glaze the tart with some diluted jam (strawberry, rhubarb, or even apricot). This adds a glossy finish, but totally optional.
Notes
No rhubarb, make this recipe with pears, figs or peaches.
