To Buy: 
Fresh borlotti beans are available from late Autumn through to Winter. Dried beans should be purchased from a store with a  high turnover of dried beans (rather than the supermarket). Greek or Italian stores are usually the best. 
To Store: 
Fresh beans should be stored in a dry cool pantry or the fridge. Store dried beans in a dry airtight container. Dried beans will keep for years - but obviously the best flavour are from those that have just been newly dried. 
Tips & Tricks: 
If you have forgotten to soak the beans overnight - pour boiling water over them and soak for three hours before cooking with fresh water. 
Cooking Tips: 
Cook fresh beans for approx 30 - 40 minutes until tender, adding salt to the water in the final 5 minutes. Dried beans will take between 1 - 2 hours depending on the age of the bean and the length of soaking. 
Cook them in stock with sauted vegetables for a delicious comforting winter dish.
