Store your fresh Thai Basil in an airtight container or bag in the refrigerator.
Most fresh herbs freeze well, which is handy if you’ve gone and bought the biggest bunch of seasonal herbs… but only needed a few leaves. To freeze always thoroughly wash your herbs, leaving them to dry on a paper towel. Once partially dry, chop finely and pop them in an ice cube tray, filling the tray with water. Good herbs to freeze include dill, parsley, coriander and chives.
Another option is to dry your fresh herbs. Simply tie them in a bunch and hang upside down in a cool, dry place. Particularly good drying herbs include Rosemary, thyme, marjoram, mint and oregano.
