I got hooked on Curry Rice while in Japan for several years. Today when I wish to prepare Curry I go to the local Japanese Market and buy an 8.4 oz. (240 g.) box of S&B Golden Curry which is offered in several degrees of "hotness" or spiciness. I prefer "Mild." According to the directions brown your meat of choice in a pan with oil or butter, add diced onions to saute then throw it into a pot with your diced potatoes, carrots, water and any other ingredients you desire and add the curry paste. Simmer and stir until its (the Curry paste) all melted and smooth and the veggies are fully cooked then enjoy.
I've tried Thai Curry at a local restaurant which is prepared with Coconut Milk and that is tasty too. Frankly, I prefer the Japanese style.
Curry is one of those magical foods that just hits the spot that others aren't able to.
