It's easy! Simply portion some of the batter into a measuring cup and pour it in a thin stream in a circular/criss-cross/zig-zag into the hot oil. This method is the easiest to clean up and has the smallest chance of spills--I love it! If you are having trouble getting a thin stream, you can also pour your batter into a piping bag fitted with a large round tip (1/2" diameter). Plug the tip with your finger, portion the batter, and then pipe it into the oil.
