Do you know that the taste of filo pastries largely depends on what kind of oil you are going to stretch this dough with? For vertuta I like to use a mixture of butter and sunflower oil in a ratio of 5:1. Chef Andrei Velichko stretches out the dough in sunflower oil. But you can use any kind of oil, for example, olive oil, which will give Odessa pastry a light Greek touch.
