If it’s difficult to get self-rising flour at your supermarket, make your own. ‘Just add 2 teaspoons of baking powder for each 150g/6oz/1 cup plain flour’ (Nigella Lawson).
It is easier to take the cake out of the metal cup. After steaming, leave it to cool for 5 minutes and it will almost fall out immediately. The earth ware cups are different. The cake will only come out nicely when you leave the cake to cool for 15/20 minutes. Make sure you rub the molds with butter or oil before you pour in the batter or use cupcake liners.
I make my kue today with the food coloring: pandan paste (green) and rose syrup (pink). They are best eaten warm. Our whole house smells like coconut now. I love our lazy Sunday afternoons ;-).
