Wash the apricots and cut them into thin slices. Place them in a larger bowl, cover with granulated sugar and leave to rest for 4-5 hours. Then pour the mixture into a saucepan and bring to a boil. Cook for about half an hour and then strain through a fine sieve.
Pour the apricot syrup into a glass container, add alcohol, apricot kernels and close the container. Leave the closed container with liqueur to mature for 3 months in a dark and cool place.
After three months, pour the liqueur into resealable glass bottles. Cheers!
