The bunch of them in my fridge will be happily awaiting your response!
Sent by KatieEditor: Katie, my personal view is simply that the white and green parts of scallions have different textures, and to some degree, tastes. When cooking scallions I like to put the white parts in the pan a little sooner, since they need a bit more time to get tender. If I added the green parts at the same time, they would be slimy and overcooked by the time the white parts were done. That's a very broad perspective, but it's a place to start.
Readers, do you have any rules of thumb on how you deal with scallions?
