All of these items are usually bought at local markets, although some people may have a garden where they grow onions. So, the dish I ate contained food that is farmed in one season to provide food year-round (corn), food that is foraged (kapokia leaves), food that is made from local tree products (palm oil and chotu) and food that is bought at market (salt, dried fish, onion and bouillon cubes). Food comes from many sources!
