These go with Chicken Soup I posted. Don't forgo the refigerated resting period that is in the recipe or you will get what my Father lovingly decribed my Mother's Knaidlach as "Bull-killer's"! They were so heavy!
Crack eggs into a large bowl and beat with a fork to mix thoroughly. Beat in the schmaltz, salt, pepper and baking powder. Stir in matzo meal, then mix vigorously with a wooden spoon until completely blended and very stiff. Cover with plastic wrap and refrigerate for 30 minutes.
Fill a large pot 3/4 full of water and add 1 tablespoon salt, bring to a boil. Wet hands with cold water so the batter doesn't stick, shape a bit of mixture into balls the size of ping-pong ball. They will double in size when cooked. Gently place in boiling water, decrease heat so that water simmers briskly and cover pot. Cook for 25 minutes, don't remove lid. Remove balls from water and serve with the chicken soup.
