You are one of the few people I know that use Savory.
I learned about it from a pizza place in my old neighborhood.
They've won many awards with their pizzas over the years, and they are somewhat famous in New Jersey (mostly due to their location between highways, lol).
I've heard people have tried to duplicate their recipe, but no one could ever guess what their secret was.
One day I was cleaning out a cupboard and found a bottle of savory in a spice rack that was years old. Before I tossed it out, I tasted the Savory and voila'! That was the secret ingredient in the pizza.
Tjey not only use it 50/50 with Oregano in their sauce, but they also sprinkle a little on top of the assembled pizza.
Try Savory on a pizza in lieu of or in addition to Oregano sometime.
