The crushed shells come from a whelk processing factory. The locally caught whelks are prepared and shipped to South Korea where they are eaten in a delicious spicy salad called “golbaengi-muchim”. A popular national beer food. We’re very proud to make use of the humble whelk in its entirety – a yielding little gastropod for both the garden and stomach. Great for plant pots and terrarium dressing, beds and borders as well as a natural pest control/deterrent.
