The recipe I am refer to Yuzu chffion cake
The filling itself I use cream puff custard sauce [here] and replace the sugar with the same amount of yutzu sauce..
The difference between chiffon and swiss roll, the egg whites need only to beat until soft peak, if the egg white is too hard, the cake might break easily upon rolling.
But my rolling skill sucks.. have to practice more..
Next one on my to do list is Thai tea swiss roll.
