In Japan, cucumber rolls are called kappamaki, and they happen to be one of the most popular sushi rolls.

Making sushi rolls requires a careful attention to detail, but they're not hard. In fact, this is a good recipe to start with if the process is unfamiliar to you because it only requires three ingredients: nori (dried seaweed), sushi rice, and cucumber. As there is no fish included, this roll is also perfect for vegetarians and vegans. (It also happens to be a roll that children in Japan enjoy.)

The word kappa doesn't actually mean cucumber in Japanese (that is kyuuri); it refers to a demon or imp figure from Japanese traditional folklore whose favorite food was believed to be cucumbers. The word kappa is related to water; it's a combination of words meaning "river" and "child." And so, kappa is associated with cucumbers, hence the name of this sushi roll. Interestingly, no other Japanese cucumber dishes are called kappa.

This recipe calls for Japanese cucumbers, which are long, slender, and thin skinned. They do not have seeds or any bitter taste and are therefore easy to handle and a pleasure to eat. If you cannot find Japanese cucumbers, mini Persian or English cucumbers are good substitutes. In a total pinch, you can use garden-variety cucumbers, but be sure to scrape out their seeds.

"These delightful rolls are a great introduction to authentic sushi making and eating. This Kappamaki recipe makes simple, small rolls with few ingredients so you can savor the refreshing, crunchy cucumber paired with chewy sushi rice and nori. Simply wonderful!" —Diana Andrews

  2. Wrap a bamboo mat (makisu) completely in plastic to keep the nori from sticking to it. Put a piece of nori on top of the mat lengthwise.

How to Store Kappamaki

As with most sushi rolls, kappamaki is best and freshest the day it is made, but it will keep for a day or so if need be, covered in the refrigerator. You can make the sushi rice, which is a stickier rice, ahead of time, or slice the cucumbers a few hours ahead of time, or the night before, to ease the prep process.
