Happy birthday to Bart!
My sourdough starter turned 12 years old today! And since I promised you the recipe for these blueberry kolache in the last reel, I figured today was the perfect day to finally share it.
This dough recipe has a little family history behind it. My mom got the original recipe from my grandma, so it’s been in our family for quite a while. The only thing I changed was turning it into a sourdough version.
It’s a wonderfully versatile dough for all kinds of kolache—filled with fruit, nuts, or, like these, a creamy farmer’s cheese filling topped with fresh blueberries and buttery streusel.
PS: And if you noticed the blue-and-white plate in the photos—it’s decorated with traditional Haban folk motifs. I’m from a town with the largest historical Haban settlement, so seeing these patterns always feels good ♥️
So, as promised, here’s the recipe:
Blueberry Sourdough Kolache
Dough
100 g active sourdough starter (100% hydration, white wheat)
200 g all-purpose flour
200 g bread flour
40 g egg yolks (2 large)
110 g butter
60 g sugar
4 g salt
5 ml vanilla extract
160 g milk
20 g dark rum
Farmer’s cheese filling
225 g farmer’s cheese
1 medium egg yolk
20 g honey
20 g powdered sugar
5 ml vanilla extract
5 ml lemon extract

1 egg, for egg wash
Fresh blueberries, washed
Streusel

A 12-year-old starter, a recipe passed down through three generations, and one of my favorite summer bakes.
Enjoy! 😊
