Umeboshi are pickled sour ume, a fruit often identified as a plum though it is more closely related to the apricot. They are most commonly eaten with rice which mellows their salty and sour taste. Purple leaved perilla, which colours the ume red, is sometimes added during the salting process. A more modern preparation of umeboshi includes honey to slightly sweeten the finished fruit. I thought I’d dip my toe in the umeboshi pool so I bought the latter.
Recently, I visited a local Japanese grocery store and came home with some goodies including a container of the honey version of the umeboshi and made a batch of umeboshi onigiri.
Clockwise from the top: Adzuki beans, mochiko (sweet glutinous rice flour), katsuobushi (shaved dried bonito flakes) and umeboshi with honey. The sushi rice was purchased from my local grocery store chain because the price was better (8 kg for $13.99).
I DID make a traditional triangular shaped onigiri with the pitted umeboshi in the center but my preferred presentation was made by adding diced umeboshi to the cooked sushi rice and shaping the rice into rounds. Normally one shapes the onigiri using dampened hands sprinkled with salt to season and help in the preservation of the onigiri. However, the salty umeboshi added to the rice eliminates the need for the additional salt.

Whole and pitted umeboshi
Umeboshi onigiri served on home grown green perilla (shiso) leaves.
The onigiri may be wrapped in a half sheet of nori, along with a perilla leaf for flavour, wrapped with plastic food wrap and frozen for quick meals. Or, if you like your nori crispy, wrap the onigiri separately and add it to your lunch box/bento along with a half sheet of nori. You may serve the onigiri with a bit of soy sauce, if you prefer.
Spoiler Alert: Mochiko flour is an ingredient in a number of sweet or savoury Japanese treats. Just sayin’
