Curry Rice On The Go

Today I decided to make some Japanese curry rice (kare raisu) at my office for lunch. For those of you not familiar with the dish, here's what it normally looks like:

As you can (kinda) see, it's not really anything like Indian curry, except it does use curry powder/garam masala. It's more like a thick stew with curry spices, apparently it's based on "English curry"... I could Google it to better inform myself, but I don't feel like it.

Normally kare raisu is made with potatoes, carrots, onions, some kind of meat, various spices and quite often something sweet like apple and/or honey. It's very popular in Japan and is eaten in restaurants and made at home; families and restaurants usually have their own secret recipes. Per the name, it's served with short-grain sticky rice, or sometimes over a big piece of fried pork (tonkatsu). And... sometimes over spaghetti... the Japanese have some interesting takes on Western food, but I'll talk about that some other time.
