Hmm...when it's raining, the common tradition of Indonesian people they will eat gorengan (all kind of fried food). Rissoles is one of them. Snacking rissoles is also our favorite.
Although it has been popular since long time ago, I believe rissoles doesn't originally come from Indonesia. Some said "Rissoles" came from Portuguese by its name.
I think making rissoles is easy but it takes time as it has a couple steps before frying.
