Transfer the dulce de leche to a saucepan, add the heavy cream and heat until the dulce de leche dissolves.
1 can dulce de leche, 250 ml heavy cream
Set the mixture aside to cool.
Pour the vodka into the cooled mixture, add salt and mix thoroughly - I blended everything with a blender.
500 ml vodka
About half a teaspoon of salt was enough for me, but check the taste and add more if necessary.
0.5 teaspoon salt
Transfer the liqueur to a bottle and let it sit overnight for the flavors to "meld".

P.S.I've made this liqueur several times, and when I didn't have time or didn't feel like heating the dulce de leche, I simply put it into a large jug blender and blended it on high speed with the heavy cream. Once the mixture was smooth, I added the vodka and salt.Enjoy!
