To Buy: 
Select strawberries which are plump, bright and even-coloured. Use your nose to select those with a sweet, full-flavoured fragrance. Check pre-packed punnets carefully and avoid bruised, mouldy fruit at the base and sides of the punnet. Avoid insipid, pale, unripe berries.  
To Store: 
Remove them from the plastic punnet and lay on a sheet of paper towel in a single layer. Cover with plastic wrap and refrigerate for up to 3 days.
Tips & Tricks: 
Wash and hull only when ready to use. 
Cooking Tips: 
I don't know of any better way to eat a strawberry than to eat it as it is. Straight from the farm. 
Another interesting way to prepare strawberries is in balsamic vinegar. Soak a punnet of good strawberries in 3 - 4 tbsp best quality balsalmic vinegar, sweetened with 2 - 3  tbsp sugar. Soak overnight in the refrigerator before serving.
