Peel the rhubarb stems and cut at an angle pieces.
Make sure you have passed the hibiscus throught cold water before use.
Over low heat, combine and bring to a boil the water, rhubarb peels, hibiscus and sugar.
Add out of the heat, the pieces of rhubarb, cover and let infuse at least 1 hour..
Preheat the oven to 180°C.
Mix the almond powder, salt, icing sugar and flour sieved (the dough can be done by robot).
Add the cold butter and incorporate with your fingertips until you get a consistency of sand.
Add the egg, incorporate without too much handling the dough and form a ball.
Film and put in the refrigerator for 2 hours.
Flour the kitchen counter slightly and roll out the dough to 3 mm thick.
Place the dough in the mold, and remove the excess on the edges with a knife.
Add a baking sheet to the dough and lay clay beads or dry beans to prevent the dough from rising. If you have none of this, prick the dough in several places with a fork.
Bake for about 30 min, until the edge is golden.
Meanwhile, bring to a boil the milk and the split vanilla pod.
Whisk the egg yolks and sugar until the mixture bleaches.
Add the sifted flour and whisk again.
Pour half of the hot milk on the preparation.
Pour everything into the saucepan containing the other half of the milk.
Over low heat, constantly whisk the preparation until a thick consistency (about 3 min).

Drip the rhubarb and lay out the pieces on the cream.
Plating suggestion: For a graphic presentation as in the photos, I advise you to make the drawing in an empty mold and transfer to the pie once everything is in place. Start with the edges by forming rafters around and fill with lines.
