If you happen to visit Malang (East Java), do not skip the chance to visit Bakpao Telo right in Lawang, a small city just before Malang. The shopping complex is located conveniently on the main street, its enormous size makes it impossible to miss. What is unique there? A lot of assorted snacks (cakes, cookies, chips, and many more), made of highly-nutritious sweet potatoes, known here as ubi jalar or ketela rambat, often shortened to tela or telo, hence the name.
Needless to say, the following delicious steamed sponge cake (bolu kukus), which costs me a fortune (20 Eurocents or a quarter dollar), is my favorite.
