STEP 1/8
Add 2 bags of coffee to 50ml of hot water and make it strong in advance.
The egg separates the white from the yolk. Beat meringue in a bowl with separate whites.
STEP 2/8
Add sugar in three equal portions. When it starts to bubble up, stir it quickly, and when the meringue starts to catch, add a third. Properly made meringue won't fall off even if you flip it slightly.
STEP 3/8
Beat quickly, adding yolks one at a time to the meringue. Stir 1 minute for each yolk.
STEP 4/8
Sift the flour and baking powder from the above ingredients, sift it, then add coffee and cooking oil (butter) and mix well.
STEP 5/8
Spread the oil or butter thoroughly so that the batter does not stick to the inside of the electric rice cooker.
STEP 6/8
Fill it with the batter and lift the container inside the rice cooker about four to five times Drop and drain the air inside the dough. If the rice cooker has a steaming function, heat it for 40 minutes, and if it is the same rice cooker as in the picture without the steaming function, it comes up naturally in about 2 minutes, repeat 2 minutes - 8 minutes of heating 4 times.
STEP 7/8
When finished, turn the rice cooker over and take out the cake.
I made a little strong coffee and added it, but if you made it and it doesn't smell like coffee, try adding more coffee powder to the same amount of water (50ml).
