Agar Jelly with Anko and Fruit (あんみつ, Anmitsu)
Anmitsu looks like a tray of small tasks, but the work is calm: dissolve the kanten fully, chill the pieces clean, then let fruit, anko, and kuromitsu do the speaking.

Steamed Chestnut Yōkan (栗蒸し羊羹, Kuri Mushi Yōkan)
Created by
Steamed rather than agar-set, this older yōkan folds autumn chestnuts into smooth azuki paste and sets softly under steady heat. The batter should fall in a heavy ribbon, then rest before slicing.

Chestnuts announce autumn without raising their voice. In kuri mushi yōkan, their pale gold pieces sit inside dark azuki paste like a small calendar of the season. It looks severe at first, a clean brown block cut into quiet slices, but don't be bullied by its neatness. This is not difficult work. It is patient work.
The yōkan most people know is firm with kanten, or agar. This older steamed kind is softer, closer to a dense confection than a jelly. Wheat flour and a little hon-kuzu set the sweet bean paste as they cook, so the texture comes from gentle heat, not from boiling syrup into obedience. The first secret is the batter: thick enough to fall from the spatula in a heavy ribbon, loose enough that the flour can fully hydrate. Too thin and the chestnuts sink. Too stiff and the slice eats dry.
Use good koshian, smooth sweet red bean paste, and chestnuts worth showing. If fresh kuri are in shun, simmer them in light syrup first. If you use jarred kuri no kanroni, drain them well and choose whole pieces with clean edges. There is nothing hidden here. The chestnut is the season, the azuki is the body, and the steamer merely brings them together.
Make it ahead because it needs the rest. Cooling isn't waiting around with a virtuous expression, it is part of the setting. Once the starches settle, slice with a damp knife and serve three slim pieces with room around them. Leave it room, and the confection becomes more generous, not less.
Yōkan began as a Chinese term for a mutton broth or jelly, but it changed after reaching Japan through Zen Buddhist culture, where meat was avoided and azuki beans took its place. The steamed style, mushi yōkan, predates the firmer kanten-set neri yōkan that spread after agar became established in the Edo period. Chestnut versions are tied to autumn wagashi, when kuri were valued both as a mountain food and as a seasonal marker on the tea table.

Equipment Needed
- •Nagashikan rectangular wagashi mold, or a small parchment-lined loaf pan
- •Steamer or wide pot with a rack
- •Clean cloth for wrapping the steamer lid
- •Firm rubber spatula
- •Fine sieve
Instructions
- 1
Prepare the mold
Line a small nagashikan, the rectangular wagashi mold, with parchment. A small loaf pan works if that's what you have. Leave two parchment flaps over the sides so you can lift the yōkan out cleanly. Set up a steamer with enough water for a steady 45 to 50 minutes, and wrap the lid in a clean cloth so water droplets don't fall onto the surface and mark it.
- 2
Cut the chestnuts
Drain the kuri no kanroni and pat them dry. Choose 5 or 6 handsome halves or whole chestnuts for the top, then cut the rest into quarters. Drying them matters because syrupy chestnuts loosen the paste around them, and you want clean pockets of chestnut, not wet tunnels through the yōkan.
Fresh chestnuts must be cooked first. Raw chestnuts won't become tender inside the yōkan before the bean paste sets. - 3
Mix the flours
Sift the flour and hon-kuzu together into a bowl. If the kuzu is in hard pebbles, crush it first with the back of a spoon. This is small work, but it saves you from pale flour pockets in the finished slice, which look innocent and eat like chalk.
- 4
Work the paste
Put the koshian in a mixing bowl and stir in the sugar. Add the sifted flour mixture in three additions, pressing and folding with a firm spatula after each one. You're not whipping air into a cake batter. You're working the starch evenly through the bean paste so it sets as one smooth body.
- 5
Adjust the batter
Stir in the water and the spoonful of chestnut syrup, a little at a time, until the batter is glossy and thick. Lift the spatula. It should fall slowly in a heavy ribbon and sit for a moment before sinking back. If it pours like cream, it is too loose. If it breaks off in clumps, add water a teaspoon at a time.
This thickness decides the dish. It holds the chestnuts in place and gives the flour enough moisture to cook through. - 6
Fill the mold
Fold the quartered chestnuts through the batter. Scrape it into the lined mold, press it into the corners, and tap the mold once or twice on the counter to settle any hidden gaps. Smooth the top with a damp spatula, then set the reserved chestnuts on top in an uneven line. Odd numbers look calmer on the plate, which sounds like superstition until your eye agrees.
- 7
Steam gently
Cover the mold loosely with parchment or foil and set it in the steamer. Steam over steady medium heat for 45 to 50 minutes. The surface should look set and satin-matte, and a skewer pushed into the center should come out with thick paste clinging, not raw batter. Keep the heat steady rather than fierce, because violent boiling throws water around and roughens the top.
- 8
Cool and slice
Lift the mold out and let the yōkan cool completely at room temperature, then cover and chill for at least 1 hour. Unmold it with the parchment flaps. Slice with a damp knife, wiping the blade between cuts. Hot yōkan smears and lies to you; cooled yōkan shows the clean face you worked for.
Chef Tips
- •Buy koshian that tastes clean and bean-forward, not only sweet. If the paste is dull, the finished yōkan will be dull too, and no extra chestnut will rescue it.
- •Hon-kuzu gives the most refined, gentle pull. Katakuriko is a sensible stand-in and will set the yōkan well, but it won't have quite the same soft clarity. Say that plainly and you're still cooking honestly.
- •This is not the long-keeping kanten yōkan sold in firm blocks. Because mushi yōkan contains flour and moisture, keep it wrapped and refrigerated, and serve it within three days.
- •Slice thinly. A thick slab makes the sweetness feel heavy, while three slim pieces with empty space around them let the chestnut and azuki speak clearly.
Advance Preparation
- •Kuri mushi yōkan is best made the day before serving. The texture settles overnight, and the slices cut more cleanly.
- •Keep it tightly wrapped in the refrigerator for up to 3 days. Bring it back toward room temperature before serving so the azuki tastes round rather than cold and muted.
- •If using fresh chestnuts, cook and peel them a day ahead, then simmer them gently in a light syrup until tender. Cool them in the syrup so they stay moist.
