That’s a cousin of the baba au rhum (Rum baba), famous in my place of origine.
That was a way to recycle dried sesame potica :
The cake was soaked in a light syrup of awamori (sweet rice sake) and kurozato (Okinawa black sugar).
It’s the custom to serve the baba au rhum with cream (whipped or custard ) and with fruit salad.
Here grapes and whipped silky tofu.
Served very fresh, that was good like a sin !
Another way to recycle brioche/chinois/potica…
