Watercress grows plentifully in the stream by my mother's house (zone 6). She found a calm part where the water flow is very gentle, very minimal, and has propagated a little watercress colony.
She brought over a bag of fresh watercress recently and I obviously turned to Pinterest to find a recipe to use it. This little salad was super simple, easy and quick, and used some interesting blanching techniques that I'd never tried.
