To Buy: 
Buy fresh bunches, buy them in a pot or grow from a seed. 
To Store: 
Store fresh mint wrapped in damp kitchen paper and placed in a plastic bag in the crisper section of the refrigerator - for about 5 days. 
Store dried mint in an airtight container in a dark, dry place - keep it away from other dried herbs as the flavour will take over. 
Tips & Tricks: 
The oils in mint are in glands in the leaves. Crushing them releases the oils and the pleasant, strong and soothing flavour. 
Cooking Tips: 
Combine fresh mint with parsley to make fatoush and tabouleh. Add it to natural yoghurt for a refreshing accompaniment to curries. Mix in with couscous. Serve with lemon and water in the summer. There are so many things to do with mint, it's always worth having a pot growing nearby.
