In search of "peach buns" (shou tao).
You can buy them frozen at most markets like 168, 99 Ranch, or Hong Kong.
You can also pre-order them (I think minimum is something like 2 dozen) at many bakeries. Try Cathy's Bakery in San Gabriel.
By the way, when you say "shou tao" I take it you mean those "long life buns" that are made to look like nectarines, but are filled usually with sweet red beans or lotus paste, right?
We always get shou tao for my grandma's birthday unless she's out of the country. My mom always takes care of this so I had to do a little research. I think the bakery is called Best Bakery. It's in Alhambra on Valley a little past the plaza with a Big Five Sporting Goods in a shopping center with a Chinese supermarket. I hope those clues help since I'm not 100% about the name because they have the best shou tao hands down. The buns are large and very pretty. They have to be special ordered as well and you can get them with a red bean paste or date paste filling. JJ Bakery also has them if you special order as well.
