I didn't know people actually grow pumpkins in Istria. Do they make pumpkon oil as well? I thought this was more common in Međimurje and Slavonija. Also, it was awesome to see pumpkin plant still in blossom so late in the Autumn, when most of the pumpkins are ripe.
I think they make oil nowadays. When I was a kid, I remember pumpkins being grown mainly for feeding the pigs. Only in the central part of Istra, around Pazin, I encounter larger fields covered with pumpkins.
