Twice a week, I see this 75 years old man selling braised peanuts and Bogor peanuts in front of my office building.
3 hours of cooking in boiling water with a pinch of salt to make the peanut soft and tender.
These are Kacang Bogor (Bogor peanuts) named after a city "Bogor" which located 60 Km from Jakarta and well known as the Rainy city.
A cup of peanut costs Rp. 3.000
