Sis forSesame seeds
Scientific name: sesamum indicum
Sesame seeds are the seeds of a plant from Africa and India that grows to about a metre high. The seeds can be pressed to extract the oil but are used most often sprinkled on other foods as a flavour and garnish. You often see them stuck to the top of loaves of bread.
The sesame seeds in the picture are on top of some cooked spinach.
