Place all the above ingredients in a jar, cover with a lid and shake vigorously.
Take a teaspoon and drizzle small amounts of the marinade over each oyster just before serving.
For a more intense flavor; spoon over the oysters one hour before serving.
Note that this recipe is intended to have a fair bit of kick. If it is too spicy, remove the chili seeds before chopping. And if you feel there's a little too much alcohol, hold back on half the gin.
