Mandarin Orange Dorayaki (โดรายากิส้มแมนดาริน)

1.Prepare the dorayaki batter by whisking together the eggs, sugar, mandarin mix concentrate, and water until well combined. Sift cake flour, baking powder, and baking soda into the mixture and stir until smooth.

2.Heat a non-stick pan over low heat. Spoon about 2 tablespoons of the batter onto the pan for each dorayaki and cook until small bubbles appear on the surface then flip the dorayaki. Cook the dorayaki until both sides are golden brown. Repeat until all the batter is used, making around 20 dorayaki pancakes. Set dorayaki aside to cool.

3.For the custard, whisk egg yolks with sugar, then add the cornstarch, mandarin mix concentrate, and milk. Cook the mixture over medium heat, stirring constantly until thickened.

4.Remove from the heat, add the butter, and whisk until smooth. Allow the custard to cool slightly, then transfer to a piping bag.

5.Pipe the custard onto the centre of one dorayaki pancake, then top it with another pancake, pressing the edges gently to seal before serving.
