In a medium bowl mix milk with vinegar and set aside as it turns into something like a liquid buttermilk.In a small bowl put the sifted flour, salt, sugar, baking powder and cardamom (or whichever spice you chose from above). Mix all the dry ingredients well.In a small bowl beat the egg well until frothy. Add all the liquid ingredients to the milk: melted butter, egg, milk and give it a whisk for about 30 seconds.Add the dry ingredients to the liquid batter and on the low speed of your electric mixer whisk everything until all the ingredients are incorporated.This time around I stuffed my pancakes with blueberries. A little goes a long way. Do not over-stuff the aebleskiver, as the inside will be too moist and will not cook through. Make sure the fruits you chose are not very large. Cut them in small pieces if they appear bigger.If you are using a cast iron pan, make sure you season it before placing the pancakes in it. Heat the pan on medium low heat for about 5-8 minutes. The second part of the melted butter is needed to brush the semi-circles of the pan. Again, if you are using a cast iron pan, be a little more generous while brushing.Add about a Tbsp of the batter to the individual slots of the pan. Please make sure not to top it off and keep the slots filled at â…”. Remember that you are also going to add fruits, which will add a little more volume. About now you are safe to increase the heat by just a little bit.Add the blueberries or berries of your choice at 3 pieces in each pancake.Now comes the fun part. After about a minute on one side use, the wooden skewer to latch on the inner corner (uncooked side) of the pancake and turn the pancake 90 degrees to its side. Give it another 40 seconds here and complete the full circle. In about 30-40 seconds you can give it one more roll to give it enough time to cook through. Keep using the wooden skewer and you are safe to poke the pancakes, too.I serve it with a coolie or a fruit jam. There are many options to spruce up these aebleskivers. Honey, pancake syrup, sour cream are some of the options. Enjoy and let me know how yours came out!
