The doukhobor traditional cousine mainly consists of Borsh and the spelling should be noted that if it has any letters after the "sh" added that it signifies made by another culture. IE if the letter "T" is added then it signifies that it is the Jewish reciepe as in "borsht" and not the Doukhobor receipe as in Borsh.
I note that a lot of resurants spell it with a t and in my opinion that is trying to Anglasise the work and not staying with tradition.
