I don't measure but about about 2 cups flour, 2 tsp. baking powder, 1/4 tsp. salt mixed together and I cut in with a fork about 4-5 tablespoons of Becel margarine, then I add enough milk to make a sticky mixture. The mixture is scooped up with a tablespoon and slid into boiling broth with another spoon. Once the surface is covered with dumplings, I put a tip fitting lid on the pot and reduce the heat to minimum. I leave the pot 20 minutes without lifting the lid until dumplings are done.
Make sure you have a good 2 inches of headspace in the pot for the dumplings to rise without popping the top off the pot.
