Really crazing for yam rice was this couple of days. I remember having yam rice with braised duck and that was heavenly. But i wanted to find out a faster and quick way to make yam rice and i found it on the internet. Remember, cooking is a step by step process like installing linux to your computer. Some steps can be shortcut, some steps are crucial. Follow the steps, you will achieve success. Some tips here: If you worry about pré-oil-frying the yam cubes, you can just stir fry it when you combine the garlic, chopped shrimp & shiitake mushrooms - less oil. A friend of mine microwaved the yam cubes for 2 mins on a flat plate, the idea is to pre-cook the yam before going into the rice cooker. Give it a try and let me know your results.
