1cup milk(have a few extra cups on hand if you need to thin out your filling)
For glazing kolachi
1egg yolk
2Twater
Instructions
Make Sponge
Combine all ingredients for sponge in medium size bowl. Cover, and let sit for 45 minutes.
Make Dough
Once sponge is ready: use stand mixer with hook attachment, or large bowl and floured hands, to thoroughly combine all ingredients for dough. Then, add sponge to dough.
Gently knead dough until it becomes large, airy mass. Place dough into lightly oiled bowl, cover and let rise in warm spot until doubled in size.
Make Nut Filling
Using food processor, grind together nuts and raisins. They should be about as fine as you can get them without turning them into a butter.
In a large skillet over low heat, combine sugar and milk. Gently stir until sugar is dissolved. Add nut and raisin mixture, and stir to blend. Allow to cool before using as filling.
Depending on your nuts, it's possible you'll need a little bit more milk to make the filling spreadable enough. Keep a cup of milk handy, and thin out as needed.
Assemble Nut Rolls
Once dough is ready and nut filling is room temperature, get ready to assemble kolachi. Preheat oven to 350 degrees. Divide dough into 8 equal portions. Cover the balls as you're working so they don't dry out.
On a lightly floured surface, roll out each portion to about 1/4" thickness. Spread nut mixture evenly, leaving a small border by edges of dough.
Gently roll up dough, and tuck ends under. Move kolachi to parchment or silpat lined pan, and let proof on pan for about 10 minutes before baking.
Using pastry brush, glaze tops of nut rolls with egg yolk and water. Bake in preheated oven for about a half hour, rotating after the first 15 minutes. Kolachi should be golden brown on top and bottom and feel firm to the touch. Allow to cool most of the way before slicing into rolls. Delicious warm with a healthy slathering of butter!
