This is one intimidating vegetable. The bunch I got was almost 2 feet long, with large, frilly, dark green leaves. It's all full of vitamins & minerals and antioxidants.
So I put some in soup and it was decent. Then last night, I took the remainder and stirfried it with tofu, onions, garlic, soy sauce, and rice vinegar. That's the recipe. If you measure ingredients, you're a girlie man.
So I eat this, and 3 hrs later when I'm going to bed, I start feeling warm all over and my feet were tingling. It feels like a strong analgesic; all sorts of minor aches and pains have disappeared. What is in this stuff? Now (the next day) my feet are still unusually warm. It's as though Kale is some sort of uber vasodialator.
This is a weird, but ultimate pretty good feeling. If you feel like experimenting on yourself, tell me how it turns out.
