(Cornu aspersum) Hugely adaptable and equally successful, the garden snail is the pest we all love to hate. It can be found in a range of different habitats, favouring vegetable gardens, where it consumes seedlings and strawberries with equal gusto. You can get your own back by eating it. Preparation includes fasting the snail to purge it of all unsavoury waste products in its intestine, removing it from its shell and then cooking it in boiling water. The French like to put the snail back into its shell before eating. Don’t forget the garlic butter!
