My Japanese friend offered me a bar (yes really) of curry spice she introduced me from Japan because she knows I really like chicken katsu curry. It appears as though a treat however, you discontinue squares also it helps make the curry sauce. She got me this brand .
I requested her if the only agreed to be a ready meal (like our same as getting curry sauce inside a jar) and actual cooks in Japan allow it to be correctly with spices and she or he stated no, it's not considered authentic unless of course you are making it while using packaged curry block. (She's an excellent prepare too!)
This really is simple to buy within London however if you simply're not, and don't live near an Asian grocery store or wish to make an online purchase, it appears it's relatively simple to create something on your own that approximates as to the it tastes like while using curry bar:

You actually need special japanese breadcrumbs, and oriental curry sauce - ours is available in a pot that states Fish Brand Chinese Curry Concentrate - it tastes like up-market nick shop curry sauce (also is exactly what the Wagamamas version tastes like). You combine it with water, you will get it from most Chinese/asian food shops.
There's a Japanese junk food chain within the Asia that sells only katsu everything - you select pork, tofu, chicken, steamed eggs etc. on the plate with curry sauce and grain. yummy.
