Well, I've never seen that written with a "B".
I've never had that sort of "Finland Breakfast" either, must be because I've never learned to smoke cigarettes. Smoking fish is another thing.
"Plörö" used to be popular during the Prohibition 1919-32. Coffee houses used to sell it, as well as "Hard Tea". It's pronounced somewhat like "blur-uh", reminiscent to the sound of pouring liquid into a pot. The letter "ö" in Finnish is pronounced like the indefinite article "a" in English - not like the letter "A".
