Finding inventive ways to make use of leftovers is a problem home cooks have no matter what country they’re in, so it should come as no surprise that Japanese cooks have been putting their excess portions of curry to good use for decades, stretching them out as fillings for doughnut like breads or turning them into soups. Karē udon is a perfect example of this respectful attitude towards “waste” food, by adding leftover pork and vegetable curry to a fishy broth and some thick, chewy noodles you can create a wholesome, warming dish perfect for getting you through these freezing Winter nights. It might not seem like the obvious choice to use a dashi based stock for this soup, but it creates a wonderfully rounded savoury flavour rather than anything particularly fishy tasting. This combination of dashi, sake, mirin and soy sauce as a soup stock is known as mentsuyu, and is the classic starting point for many udon and soba dishes, even being used as a refreshing dipping sauce for cold noodles.
Karē udon, perhaps one of the country’s most popular comfort foods, has the same effect on the Japanese as a plate of macaroni and cheese might on an American or a bowl of hotpot on a Lancastrian. It has the incredible power of evoking nostalgic memories of childhood, relieving emotional stress and giving a feeling of the security of being at home, somewhere you belong. Not bad for a bowl of soup.
