Monaka Japanese Wafer Shells — Square

Monaka is one of Japan's classic confections: a filling sandwiched between two thin, crisp wafer shells. The shells themselves are the craft. They are not batter — they are mochi: pounded glutinous rice, pressed into a mold and toasted until crisp, with no sugar and no oil.

These square shells come from a monaka-shell maker in Kanazawa that has worked mochi rice since 1877. Using a single contracted rice — Shin Taisho Mochi from the Hokuriku coast — the company buys the grain as brown rice, cold-stores it, then mills and grinds it fresh for each production run. It is the same rice and the same maker behind our Round Monaka line.

This page collects the square formats. The variants differ in size and fold; dimensions are shown in the product images.

Ayako, Umami Curator at The House of Umami, toured the workshop and watched the shells take shape. What stayed with her was learning that the shell is built on a mochi base — rice, pounded and pressed, not poured. She also watched the company's in-house mold-makers at work, preserving a specialized craft that few producers still maintain. The speed and precision of the experienced artisans left a lasting impression.

A square shell plates differently than a round one, with clean right angles, a flat base that stays put, and a bite-sized scale perfect for amuse-bouches and petits fours. The crisp shell holds its shape with creamy, savory, or frozen fillings.

Each pack is labeled with a minimum guaranteed pair count. These square shells travel well and rarely break, but we pack more than 10% above the stated quantity to account for handling in transit. The labeled count is the quantity you can confidently expect to receive; in practice, most orders include additional shells.

Available to professional buyers. For larger or custom orders, please contact us.

To re-crisp: warm the shells in an oven or toaster for a few minutes before filling — the maker adds slight humidity so they survive shipping, and gentle heat returns them to their original crisp.

Fill just before serving so the shell stays crisp against the filling. Pair two halves for a closed monaka, or serve open-faced as a single bite.

Application by dish
・Amuse-bouche: pipe in a savory mousse, whipped tofu, or chilled corn — one bite, clean edges
・Seafood: a square of uni, marinated salmon roe, or seafood tartare, finished off-heat
・Foie gras: a thin slice or a piped torchon, with a dot of fruit gel for contrast
・Ice cream / sorbet: a miniature ice cream sandwich for a petit-four course
・Bean paste (classic): an, shiro-an, or yuzu-an for a traditional monaka
・Ganache / chocolate: pipe and set for a plated dessert bite
・Cheese course: a soft cheese with a smear of honey or miso caramel
・Caviar service: a crisp neutral base in place of a blini
・Vegetable: a spoon of ratatouille, mushroom duxelles, or eggplant for a vegetarian bite
・Petit four tray: fill an assortment and serve as a composed sweet course

Plating tip: the flat square base sits without rolling, so the shell stays put on the plate — useful for a row of identical single bites.

The maker adds slight humidity to protect the shells in transit; re-crisp in an oven or toaster for a few minutes before use.

Store in a cool, dry place away from direct sunlight, heat, and humidity.

After opening, press out excess air and reseal, or transfer to an airtight container with a desiccant. Shells may be refrigerated or frozen.

Best before: 270 days from production date.
