Oden (おでん) is a Japanese stew that's simmered in broth until served. It's something of a Japanese soul food — a source of warmth for cold winter days.

Oden is usually served by the piece (rather than by the bowl). Japanese hot mustard (karashi, からし) is provided as a topping.

60 Year Old Broth

The best known oden restaurant is Otafuku (大多福) in Asakusa , Tokyo. It's been opened since 1916.

Oden is simmered for long periods of time in a light Japanese dashi broth. At Otafuku restaurant they haven't changed their broth since the restaurant burned down as a result of the firebombing of Tokyo in WWII.

Water and ingredients are continuously added to the broth but the broth is never changed. Each evening, the broth is carefully put in a large bowl and the stewing vat is cleaned. When the vat is clean the broth goes back in. They've been doing this since 1945.

Aged broth gives oden an edge that warms you up. Most oden restaurants endeavor never to change their broth — a 10 year old broth isn't unusual. Otafuku's 60 year old broth is considered the current champion.

Convenience Store Oden (コンビニ おでん)

Some Japanese convenience stores sell oden in winter. As at Otafuku restaurant — the broth often looks like it has been sitting there forever. Nevertheless, people love it.
