Dorayaki (Red Bean Pancake Sandwich)

Variations

• Change the filling: custard, cream and strawberry, candied chestnut, or red bean with butter. An-butter is common in Japan for a reason — the salt and fat cut across the sweetness. Anything cream-based, though, throws away the keeping quality: eat it the same day.
• How it differs from taiyaki and monaka: taiyaki pours a thin batter into a mould, so its shell is crisp, while dorayaki is a soft castella-textured cake. Monaka is not baked batter at all but a dry wafer shell.
• Nure dorayaki: syrup brushed over the filled cake to keep it moist — a version made for eating a day or more later.
• One pancake, folded: bake one large round and fold it into a half-moon. Harder to get wrong, and it takes more filling.
• Against pancakes and hotteok: pancakes go the milk-and-butter route and dorayaki goes the honey-and-mirin route — they are not the same batter. Hotteok is the other approach entirely: a yeasted dough, filled and pressed flat as it fries.
• The name, and Doraemon: dora means gong (銅鑼), and the usual explanation is the shape of two rounds stacked. Most people outside Japan know the cake through the cartoon, but the cake is very much older than Doraemon.

Tips

• Honey and mirin are what define this. Honey is hygroscopic and holds moisture in for days; the sugar and alcohol in mirin build the surface colour and gloss. Drop both and use sugar alone and you have made a small pancake (what sugar does).
• The unspeckled face comes from wiping the pan. This is the step most often got wrong. Where oil pools, that spot fries and goes dark; on a dry pan you get even colour. Oil is something you brush on and then remove — and re-wipe between every pancake (browning).
• Low heat, thoroughly preheated. On high heat the outside colours before the middle sets. One trick is to touch the hot pan to a damp cloth once to even the temperature out (heat control).
• The 30-minute rest is a step for appearance. The flour takes up water and the large bubbles from mixing disappear. Skip it and the surface keeps pinholes — it tastes the same and does not look like dorayaki (choosing flour, dough and gluten).
• One spot, from a height, in one pour. The batter has to spread by itself for the circle to be clean. Pushed out with a spatula it ends up uneven in thickness and cooks unevenly.
• The cue to flip is the surface, not the clock. Holes rising and the gloss going means the underside is done. Two minutes is the target; your pan and your hob will differ.
• Write off the first one. Anything cooked before the pan settles comes out patchy. That is calibration, not failure.
• The damp cloth is not optional. A freshly cooked dorayaki skin dries fast, and a dried skin splits when you fold it around the filling. Stacking them under a cloth solves it.
• Dome the paste in the middle. Spread flat, it escapes at the sides and the rim will not seal. Leave the outer centimetre bare (wrapping and sealing).
• Throw away the beans' first boiling water. The astringency (saponins) leaves with it. With shop-bought paste this is already done for you (soaking).
• Sugar only once the beans are fully soft. Sugar added early tightens the skins by osmosis and the beans stop softening. That order applies to pulses generally.
• Better the next day, and keep it out of the fridge. With the honey holding water it keeps two or three days at room temperature. Refrigerated, the starch retrogrades and it goes dry and crumbly — to keep it longer, wrap individually and freeze, then thaw at room temperature (freezing and thawing, serving temperature).
