It's pronounced 'go-wom-b-ki' When you say it quickly you'll hardly hear the 'b' sound. The important thing is it's a 'wom' sound, not a 'lum' sound in the middle. Impress your boyfriend not only with your cooking but with your Polish pronunciation :))
Jon's recipe is a good basic one. True Polish cooking contains simple, rustic ingredients, no bells and whistles but every family in Poland tends to have their own version with slight adjustments. I use a mixture of pork and beef, I grate the onion rather than chop it, I add an egg to bind the mixture and some finely chopped cabbage from the left over leaves and stalks. (You won't use all of the cabbage because some of the leaves will be too small.) I also add chopped fresh tomatoes to the sauce, but you could used tinned ones.
Choose a medium sized cabbage rather than a very large one as you'll get more usable leaves from it. The larger cabbages have very big outer leaves but the inner leaves tend to be pretty small and very thick as do the stalks. I was advised on choosing the right cabbage by an old guy down in the fruit and veg market who said this was the size his mother used - and he was right!
They're really easy to make. Most Polish dishes are pretty straightforward but tend to be very labour intensive and time consuming.
