These sweet potatoes are rich with heavy cream and butter. The batter is soft so it is easy to pipe!
I've got big and tasty sweet potatoes. I tried to make large sweet potato cakes with them.This is a soft batter, so you can make also make a tart filling with this batter!
Since the potatoes may clump at the piping tip, making it difficult to pipe out the mixture, you should mix the sweet potato mixture until very smooth, leaving no lumps.If you fill your piping bag too much, you won't be able to squeeze the mixture out well and it will be difficult to pipe. Pipe the batter in batches.
Enjoy Japanese food around the world.
