About this dish

Kanko-yaki are filled dumpling-like buns from the Tsukui area of Kanagawa.

A lightly sweet wheat dough raised with baking powder may enclose adzuki beans, pumpkin, dried daikon, mushrooms, or pickles; this version uses mashed kabocha for a clear, reproducible filling. The shaped buns are browned on both sides before steaming for 10 minutes. That two-stage method gives the wrapper toasted color and aroma while the steam cooks it through and keeps the pumpkin center moist.

Instructions

Read the steps as a cooking flow: prep, heat, seasoning, doneness control, and finish.

6 steps

1

Prep

Seed 500g kabocha and cut into 3cm pieces.

Steam for 15 minutes until easily pierced, then mash finely with the skin while hot and cool.
2

Season

Mix 500g flour with 10g baking powder and sift twice.

In another bowl, whisk 260ml water, 1 egg, and 40g sugar until the sugar dissolves.
3

Control

Pour the liquid into the flour and knead for about 6 minutes until the dough is as soft as an earlobe.

Cover to prevent drying and rest at room temperature for 1 hour.
4

Step

Divide the dough and kabocha filling into 12 portions each.

Flatten one dough piece to palm size, enclose one filling portion, pinch firmly closed, and flatten slightly.
5

Control

Cook the kanko-yaki in batches in a heated dry pan over medium-low heat for 3 to 4 minutes per side.

Adjust the heat so brown spots form without burning.
6

Step

Arrange the browned buns without touching in a steaming steamer and steam for 10 minutes.

Rest off the heat for 2 minutes, then cool on a rack to release surface steam.
