This little bag of small, rather drab-looking dried leaves transforms itself in water to produce up to 1.5 litres of vibrantly coloured, herbaceous and extremely delicious juice. Simmer the pure shiso leaves in 500ml of water for 5-6 minutes, add the included citric acid, and you have a concentrated ruby-red juice that can be watered down and sweetened for a refreshing drink on its own or kept as a stock solution to add to dressings, pickles or sauces.
Use it in the same way as our Sugar-free Red Shiso Juice to enliven granitas, sorbets and jellies. Its fruity astringency also lends itself beautifully to alcoholic drinks such as sweet sake, aperitifs and cocktails, adding an intriguing flavour and a dash of intense colour.
