Making Polish Style Coffee

How easy is it to make a traditional style Polish coffee. Ok Poland has had an interesting history when it comes to coffee. Once only for the wealthy, many poorer people had to drink either watered down types of coffee and or other grains roasted in such a way as to appear to taste like coffee. They used to drink it black (Kawa parzona), no sugar, then in the early 1900's with sugar and sometimes milk however, now it is drunk without sugar in many places but sweetened with a rather liquid condensed milk. At least that's what the Polish woman told me in the shop today!
