In a bowl, combine all the ingredients listed up to salt to taste.
Mix well and form a smooth dough, you may add some breadcrumbs, if you need to bind the mixture, I didn't need any.
Make a lemon sized ball, flatten it, put some grated cheese in the cavity, gently seal it, and form a smooth ball. Dip this in the cornflour slurry (mix the cornstarch with 2 tablespoons of water), and then roll them over the breadcrumbs to coat all over. Prepare the rest in the same way. Refrigerate for 15 minutes.
Heat 2-3 drops of vegetable oil in the cavities of the ebelskiver pan, Place the balls in the cavities, let them cook for 3-4 minutes on medium heat, then flip gently and cook until evenly browned from all sides. Serve hot with dip of your choice/tomato ketchup.
