1. Boil the large field snails for 15-20 minutes before they are fully cooked. The field snails are relatively easy to cook. Just boil the water in a pot while cooking.

2. Before cooking the snails, you need to soak them in water for about 3 hours. Add a few drops of sesame oil during soaking to make the snails spit out sand. When cooking snails, use high heat to quickly kill the bacteria in the snails.
