Pizza is another favorite in my family, right after the spaghetti. The biggest challenge was to make the sticky cheese on the top of the pizza, especially at the edges. There is an awful adhesive in Hungary, Technokol Rapid, which is so messy I can't use it for making miniatures. Its special attribute is leaving thin adhesive fibers all over the work. (And it smells terrific, it even causes headache.) But when I mixed it with some white acrylic paint, the "concoction" is perfect for melt cheese.
I made various flavors, pizza with zucchini, with mushroom and with peppers. The salami was constant. And of course I made my usual little scene, too.
