About this dish

Fukuregashi is a Kagoshima sweet steamed as a thick slab, rising strongly through the reaction of baking soda and vinegar in a flour and brown-sugar batter.

Because soda makes it plump, it is also called soda sweet, fukurakan, or fukurekan. It belongs to the region's brown-sugar food culture, shaped by the difficult history of Satsuma control over sugarcane and sugar production in the Ryukyu and Amami islands. Once served at harvest festivals and with tea during farm work, it is now eaten year-round. The texture is fluffy while warm and chewier after cooling. Wrapping the steamer lid in cloth to stop condensation and steaming for a full forty minutes cooks the thick center evenly without wetting the surface.

5 steps

1

Heat

Sift 120g flour and 5g baking soda together twice.

Line an 18cm small colander with damp cloth and bring ample water to a boil in the steamer.
2

Season

Beat 1 egg fully, then add 140g powdered brown sugar, 5ml rice vinegar, 10g honey, and 80ml water.

Whisk 2 minutes until large sugar lumps disappear.
3

Step

Add sifted flour in three additions, lifting from the bottom with a whisk.

Stop as soon as no dry flour or lumps remain so the baking-soda reaction is not lost.
4

Control

Pour batter into the lined colander and level once.

Wrap the steamer lid in dry cloth to stop droplets, then steam over medium-high heat for 40 minutes after strong steam is rising.
5

Prep

Insert a long skewer in the center; remove when no wet batter clings and the center is at least 95°C.

Cool with the cloth on a rack for 20 minutes, unwrap, and cut into 8 pieces.
