Method

• To make the dough: put the flour, baking powder, and salt in a mixing bowl, make a well in the centre
• Pour the egg, oil, vinegar, and water into the well and use baking paddle on the mixer to combine
• Once the dough starts to form, you can knead in the bowl or take it out and gently knead a few times
• Form into a ball and cover with a tea towel and allow it to sit for an hour at room temperature, while you make the filling for the knishes
• Boil the potatoes until soft, I didn't peel but you can if you wish
• While they are cooking heat olive oil in fry pan over medium heat, then add garlic and cook for about a minute, then add the kale and cook till it wilts and softens, then set aside
• Once the potatoes have cooked, drain off the water and add milk, red onion, butter and salt and pepper
• Mash the potatoes roughly then add the wilted kale and stir to combine
• Once the dough is done resting, preheat the oven to 180 degrees C
• Flour the surface you will roll the dough on and roll out until you get a rectangle shape
• Place the potato filling about 2 inches from the bottom of the dough rectangle, do this by spooning the filling into a log shape, use your hands to form it
• Then you roll the dough over the potato mix (just like you would a sausage roll)
• Once you have made a complete roll, make sure you seal the log, then pinch a ball sized pieces, twisting it (like when you make sausages)
• Then cut these from the log and join the ends, so they are sealed
• Make an indent in the top -it will look a bit like a bagel
• Then repeat the process until you have finished
• Place the knishes on a baking tray that is lined with a baking sheet, and brush liberally with the beaten egg and sprinkle each one with poppy and/or sesame seeds
• Bake for about 35 min, or until the knishes are golden brown
• They are nice eaten warm or cold
