LORELAI: I’m so happy for Sookie. I mean, it’s like a real live love story, and I saw it all happen. I mean, I hired Jackson. I watched them meet. I watched them have several bizarrely intense arguments over mustard greens. I watched them fall in love.
Mustard greens are the leaves of the mustard plant (Brassica juncea), also known as brown mustard, Chinese mustard, Indian mustard, leaf mustard, Oriental mustard and vegetable mustard. The plant has been cultivated in Asia and Europe for more than 2000 years, and is used in salads, soups, stews, and stir-fries, as well as pickles. It has a bitter, peppery flavour which matches well with beans, lentils, pork, ham, tofu, onions, garlic, and lemon.
