With all that talk, and some of the right ingredients in, I thought I'd have a go at something a little different ...
Aubergine as the base, sliced through and griddled, topped with pepperoni and buffalo mozzarella.
Buffalo milk has dramatically lower levels of the allergenic and downright nasty alpha S1 casein compared to cow milk. It's a good choice if you are happy with some dairy in your ancestral template.
No tomato? Nah, I didn't fancy it but might well next time.
Pepperoni? Yeah, I know ... what can you do?
It was fun. It'll probably be another year before I so it, or something similar, again.
