Banh Bo is Vietnamese honeycomb steamed sponge cake, made from rice flour, yeast, sugar, coconut milk and pandan leaves.  The rice cake is served as dessert with coconut sauce and top with roasted sesame seeds. In the Mekong delta, people add  more coconut milk in the cakes.

Traditional Chinese white sponge cakes  (Bai Tang Gao in Mandarin and Bak Tong Gao in Cantonese) often are used for worship and eat as snacks.  The Chinese cake does not have coconut milk in it and has more sour taste. The popular way to eat is to put a rice cake inside Banh Tieu (hollow fried bread “ham chim peng”).  On Ching Ming Festival, my family offers a lot of food for ancestor worship. We always have Chinese rice cakes with roast pork and Teochew braised ducks at the tombs.

These recipes of  honeycomb steamed sponge cakes used bread yeast (or rice wine yeast). It’s best to  review all recipes.  It may take 2 days to make successful honeycomb rice cakes, since the batter needs time to rise and ferment.  I suggest to prepare the dough starter 1 day in advance.  Let the syrup batter ferment  in a warm place  until there are a lot of foams rise up, may need more than 3 hours.

Bánh bò rice cake was originated from Mekong Delta since it has coconut cream in it.  Many people translate the name “Banh Bo” as “cow” cake is incorrect.  Since bò  in Vietnamese means cow or crawl.  And “crawl” is the best term to describe the process of “rising” or “falling” of the rice cake during steaming.
