This was second dish I made from the leftover soy beans or edamame (hulled and frozen in a microwavable pouch). I saw the original recipe on line but this is very similar to the American summer favorite succotash except for the use of soy bean instead of Lima beans and soy sauce for seasoning. The combination of butter and soy sauce is almost fail-safe and add the flavor of sweet corn, it is extremely good.
Corn: I got four ears of fresh corn. As per my wife's method, after removing the husks and silk, I placed them on a plate covered loosely with paper towels and microwaved them for 4 minutes, turned them over and microwaved for additional 2 minutes. (Of course you could boil the corn or use frozen.) My wife removed the kernels of the cooked corns for me.
Edamame: I used frozen, hulled soy beans in a microwavable pouch but fresh or frozen soy beans in pods can be also used (even better, I am sure) after cooking and removing the soy beans from the pods. The amount is arbitrary but I could have used more for the amount of corn I had.
I can think of adding other items such as finely diced tomatoes, shallot, Jalapeño pepper, red pepper etc but I made this with just corn and soy beans. I just sautéed the soy bean and corn mixture in large frying pan with butter (1 tbs) until all the vegetables are coated and warm. I then added soy sauce from the edge of the pan (so that soy sauce will be heated up quickly and become fragrant before mixing into the vegetables.) I added soy sauce in several increments as I tasted.
As we were preparing this, both my wife and I were snacking on them and without further seasoning these were good. The corn was very sweet. The addition of butter and soy sauce made it even better. This could be a drinking snack or a side dish. I served this with corn-meal crusted chicken tender loins on the top (which I did not take pictures).
