Red shiso leaves now also come in the form of a micro herb. They are usually sold as a potted version. The leaves are delicate, with a red hue overlapping into the green leaf. Shiso is a Japanese herb and is part of the mint family. Red shiso has a truly unique and complex set of flavours ranging from being a little astringent, bitter, clove, cinnamon and mint. Its wide range of taste combined with how gorgeous it looks makes it a good candidate for salads, not only as a garnish but also as a flavour enhancer.
