I'm kind of obsessed with sorrel, right now. I've always seen it listed in my herbal medicine books but I've never seen it in person- until I found some at the farmer's market last weekend. It was love at first bite!
Sorrel looks a bit like mature spinach but with a smoother texture and a completely different taste. It's tart and lemony. The only thing I've eaten that tastes like it are shamrock leaves and flowers (which are very tasty, by the way.)
I haven't experimented with it in recipes yet, as I love it simply chopped with a dollop of greek yogurt and some sea salt. Red peppers or tomatoes would be nice, too (maybe not for you nightshade- avoiding Paleo die-hards, though!) For lunch today, I had the aforementioned salad with some chicken sausage and a handful of raw hazelnuts. Very European of me!
Here is a yummy looking sorrel salad recipe.
