I have this habit of trying to get as much juice out of my lemons as possible and I keep shoving the pusher thingy down and the juice ends up coming out frothy if I shove it too many times.
I discovered the "Frothy" is "pulpy" and even though it is just frothy and makes the Lemonade milky... IT DOES MAKE YOU HUNGRY!
So now I quit beofre it gets too frothy, I frequently scoop out the pulp from the thing you shove the Lemons down into and I juice an extra Lemon or two for my mix.
