I hear that Beard Papa Cream Puffs is opening in the US. The chain is based in Japan. There is one here in Singapore in the basement food court of Takashimaya (at Ngee Ann City). They make the pastry cream every day, with real vanilla, and then load it into a chrome pastry cream dispenser. When you order a cream puff, they fill the choux pastry right before your very eyes, thus avoiding the danger, all-too-present in Singapore, of soggy pastry. They are delicious and I recommend them highly. Don't wear black because you will get powdered sugar all down your front as you wander through the Japanese grocery store.
Mmm. The line was long for a while as a cream puff craze swept Singapore, but fickle fashion seems to have moved on. Damn sight better than the BreadTalk pork floss buns everybody was obsessed with a while back. (Basically a very soft yeast roll filled with Japanese-style mayonnaise and topped with pork floss. Pork floss itself is good, like fluffy pork cotton candy, but...)
