Place everything, apart from the vodka, into a large saucepan and bring to a simmer on medium heat.
As soon as it's simmering, lower the heat right down and let it simmer for 1 minute.
At the end of the minute, take it off the heat, and leave to cool for 5 minutes, before we add the vodka.
At the end of 5 minutes, add the vodka, stir well with a wooden spoon, cover tightly with a lid or foil, and leave to steep overnight.
Double line your funnel with your muslin cloth.
Strain your Krupnik into the sterilized bottles, pushing down only ever so slightly on the contents.
Store your Krupnik in the sealed bottles, in a dark cool place for up to a year.
