One of Indonesia's most popular street food, these meatballs in soup is usually eaten as a light snack.
But don't be alarmed, because they are pretty small so they don't quite fill you up to be a meal. It usually comes with tahu (fried tofu which soaks up all the wonderful broth) and siomay (Indonesian siew mai usually made from the same beef in the meatballs and some fish paste). To up your bakso game, interesting add-ins include bakso puyuh, a personal favourite of mine, which features a whole quail egg inside the meatball. Add in sambel (chilli), tomato sauce for some sweetness, a drizzle of kecap manis (dark soya sauce) and a squeeze of lime and tuck in! Soak the fried fritters in the soup for extra shiokness, though I'll have to say the ones here were pretty disappointing but everything else was on point!
