Shiso leaves

There are two types of shiso available in Japan: green (ohba, aoba, aojiso) and red (akajiso). Shiso is part of the mint family and has a basil-like aroma and taste. It is rich in vitamins and minerals. It is commonly used as a garnish for sashimi as it is thought to help preserve and sterilise foods. Red shiso is used to give umeboshi a red colour. The flower buds from the shiso plant can be used as garnish as well. Shiso leaves are in season in summer but you will be able to find them at supermarkets all year round. The best way to store shiso leaves is to wrap them individually with wet kitchen towels and store in an airtight container in the refrigerator.
