Mon State around Mawlamyine is one of Myanmar's biggest durian-growing areas, and cooking the fruit down into a thick, spreadable jam is the local way of making its notoriously short season last months longer.
Ripe durian flesh is cooked down slowly with sugar until it thickens into a dense, fragrant jam, then jarred and sold at fruit stalls and markets around Mawlamyine. It's spread on bread or eaten by the spoonful as a sweet, pungent treat.
