Many of the words in Indonesia are being abbreviated, for example batagor is not a “real” word on its own. It is an abbreviation from Ba for Bakso (meatballs), Ta for Tahu (tofu), Gor for goreng (deep-fried). Batagor is a popular street food in the city of Bandung in West Java. But batagor can be easily found across Indonesia these days. My first exposure to batagor was in fact in Jakarta. 

Batagor is said to be an adaptation of the Chinese Indonesian Siu Mai. Tofu and wonton skins are usually stuffed with fish or meat paste and then steamed and coat with batter and deep-fried and then drenched in peanut sauce, drizzle of kecap manis, and spicy sambal sauce sometimes.
