To Buy: 
Buy fresh leaves that are not wilting or discoloured at the ends. Garlic chives will sometimes have a small tight bud on the end of them. Chives are available in a freeze-dried form, but are extremely sensitive to light. 
To Store: 
Chives should never be stored wet as they will become slimy. Wash what you are going to need at the time.  Store in a plastic storage bag in the fridge for up to 2 days.  Freeze-dried chives must be kept in a dark place to prevent fading.
Tips & Tricks: 
Because it doesn't keep for long, try growing chives in the garden. During winter remove some and plant it inside to enjoy chives all year round.  Freeze-dried chives are an excellent alternative to fresh as they reconstitute immediately.
Cooking Tips: 
Add to omelettes or scrambled eggs. Delicious in stir-fries and with savoury pancakes.
