Bánh bông lan (Vietnamese sponge cake)
Bánh bông lan is the soft, golden sponge sold in every Vietnamese bakery, eaten with coffee or as an after-school snack, and it is also the cake under the cream and fruit at most children's birthdays from Hanoi to Saigon. Made with oil instead of butter, it stays moist and springy for days and is free of milk. It contains egg and gluten. Chef's tip: whisk the whites in a spotlessly clean bowl; a trace of yolk or grease stops them rising.
