If the kitchen is the heart of the house, then perhaps the market is the heart of the town or community.
I love walking through fresh markets and supermarkets – looking at local ingredients and supplies. Find out what gets shipped across continents and become a necessity in a foreign land. Mostly finding out what is locally available and locally made.
When in Ubud, make sure to visit the main market. It is at the South-East corner of Jalan Raya Ubud and Jalan Wenara Wana, with the Ubud Palace across the street. It is very busy in the morning with a mixture of regular store owners and mobile hawkers. All happy to help with a smile.
