Crust, mix 200g flour (I used 50/50 spelt and ap,) and 1 tsp salt, smoosh in 75g cold butter, then add 1dl ice cold water and mix until just combined. Form into disk and refrigerate at least 30 minutes. Roll out to pan size and dock with a fork. Back in fridge.
Guss, 2dl milk, 100g Greek yogurt (or quark if you can get it, cream works too), 2 eggs, 1 tsp vanilla sugar, beat until well combined.
Split and stone 1kg Zwatchke (aka prunes or Italian plums. Or really any stone fruit apricots are particularly good).
Cover the bottom of the crust with 2-3 tbsp ground nuts (I used hazelnuts,but almonds, walnuts or pecans all work,) arrange the fruit, and pour over the guss.
Cook in a preheated 425f oven for 45 - 60 minutes, until the center jiggles.
Let cool at least slightly, but it's good hot, warm, or cold.
En guete!
