If you're like me and you grew up on homemade Japanese curry, you know all about the brick. A boxed, vacuum-packed tray of roux that's mixed into a simmering pot of meat and vegetables. As far as I knew, this pre-packaged mix was the only way to get down with homestyle curry.

A few years back, though, I gave up on the stuff. Turn over the box, check out the ingredients, and you'll see what I'm talking about. Because straight up? That $%#@ is nasty. Filler and chemicals. Make it from scratch instead!
