The dough in this recipe can also be used for virtually any other filling. It is a vaguely sweet, heavy, and dry dough that pairs nicely with bright tasting fruit or a heavier texture like chocolate or nuts. My family makes poppyseed rolls each Christmas, but when Grandma was around she would make walnut rolls as well.
We tend to half the recipe, which makes anywhere from 5 – 10 rolls depending on size. It is more than enough, but the full recipe is included [in brackets] for posterity. If using the full recipe, it is a good idea to use multiple fillings then freeze the remaining (whole) rolls.
• 1 packet or cake of yeast [2 cakes]
• 1/4 cup warm water [1/2c]
• 4 cups flour 
• 1 egg and 2 1/2 yolks (crack 1 yolk into liquid measuring cup, mix, and half)[2 whole, 5 yolks]
• 1/4 cup butter [1/2c]
• 1/4 cup shortening [1/2c oleo]
• under 1/2 cup sugar [3/4c]
• 1/2 pint (8 oz, according the internet) sour cream [1 pint]
• 2 tsp vanilla
• 1/2 tsp salt
• 2 – 3 standard or 1 large can of poppyseed filling
1. Pour warm water into liquid measuring cup. Sprinkle yeast on top. Set aside for 10 minutes.
2. In bowl of electric mixer, whip eggs a few minutes, then add sugar and continue to whip until slightly frothy. Then add butter, whip for a few minutes, then sour cream, yeast mixture, salt, and vanilla. After a moment, add flour and stop as soon as combined.
3. Knead for about 15 minutes. Make a ball, then elongate into a log. With a knife, cut dough into softball-sized portions for rolls that will be about a foot long. You can make larger, smaller, or even mini rolls, so cut according to what you will be making.
4. Cover with towel and allow to rise for 2 – 3 hours.
5. Roll with rolling pin and spread filling (as thick as you’d like-more is more delicious, but as I didn’t have enough the pictured roll has about 1 cm filling) from end to end. It is not necessary to leave space for wrapping as it will be cooked with the fold on the bottom.
6. Roll tightly and cover with towel. Rise 2 – 3 more hours.
7. Coat a heavy baking sheet completely with butter, rubbing with wax paper or just holding the stick and fully covering the pan. Sprinkle flour, then hit and shake the pan to coat completely. Place rolls onto baking sheet and brush with egg wash. Sprinkle sugar on top and allow to set for 10 minutes.
8. Bake for 30 – 40 minutes at 350 degrees, until golden brown. Allow to cool before eating.
