I cut up the breast into small pieces and then minced it in mini chopper together with 1 egg, 1/2 tsp. of salt, 2 Tbs. of chopped garlic chives, 1/2 tsp. marjoram, 1/2 tsp. baking powder and 1/2 tsp. of white pepper. Then I mixed in the polenta, formed it into 1-1/2” balls and slowly simmered in salted water for 15 minutes. They came out nice and fluffy (baking powder J).
These are now my favorite dumplings for a chicken noodle soup.
