Salso is popular in eastern Slavia, Poland, Baltic states. I am yet to find people who loves salo more than Ukrainians. My friend from Dniepropetrovsk was saying he’d spend his summer holidays on Dniepr taking a piece of salo and breat with spring onions. One can buy salted salo preserved in 3 litre jars in shops. One can find salo in chocolate in Ukraine. But that’s aphrodisiac. :)
