Here’s what you’ll need:
400g sweet tart dough/pie crust
1 liter white grape juice
150ml whole milk
180g heavy cream
2-3 tbs flour
2 eggs, whisked
1 tbs suger
this tart comes from romandie /westschweiz region of switzerland, aka the western portion where french is predominately spoken. thus, the reason why it’s a tarte au raisiné before it’s a traubensaftkuchen. raisiné, according to wordreference, = preserve of grape juice.
as for the german part, eine Traube = a bunch of grapes. der Traubensaft = grape juice. and der Kuchen = cake. so literally…. grape juice cake!

but let me first credit the source of this deliciousness. it comes from a book i bought last summer in switzerland. and it’s amazing because not only is it small, splits the recipes into regions, and is in french and german…
Step one: reduce your juice to 150ml. When I first read this step, I just scratched my head. Was I supposed to just pour out 150ml of the juice and use it…? Why did it ask for 1 liter then…? If not for my roommate, I probably would have done just that. But thanks to him, he explained that to reduce was to pour the whole thing into a pot and let it simmer until the water was evaporated and you are left with a really thick liquid. Okay, so I did that instead. I kept it on low heat and stirred often to avoid any burnt surprises.
While waiting for it to reduce, you can line your tart pan, let it harden in the freezer, and pre-bake it. But do what you usually do with your crust, each recipe is different. For mine, i like to pre-bake it for about 15 minutes so it isn’t as soggy.
Pour in your whisked eggs and sugar.
Then pour in your 150ml reduced grape juice. and mix.
Here is what my final “batter” looked like. I’m not sure if it was supposed to be this grainy, but it all turned out okay for me in the end.
now here’s the most satisfying part. you take that sad, lonely crust that’s just waiting for some love… and pour the yummy batter into it… and once you’ve united these two wonderful things, you know only good things can happen from this point forward.
Slide it into a 400F oven for 35 to 40 minutes. And wait.
