Each time that I used to prepare piroshki with jam or fresh fruit, it turned into a mess. There would always be a tiny hole in some piroshki that lets the fruit juice escape, causing it to mess up its siblings. But then I spotted this technique on Pinterest. It double wraps the piroshki, making a perfect result.
My boys love jam infused piroshki, seriously, my four year old ate at least eight of them in a single day.
If you wish to use fresh fruits in this recipe, replace jam with fruits instead, and a spool of sugar on top. Cherries would make a killer filling for this recipe.
For this recipe I've used my all time favorite, Perfect Yeast Dough Recipe.
