If it's any help, I only ever had it at my nonna's and she died of old age some years ago. I've thought about seeing if I could find a recipe, but I also don't want to be banned from Italy and Italian restaurants
Is your source that you made it the fuck up? The medieval book compares it to lasagne, but there's no evidence the authors went to Italy for this. If you're referring to the so-called first modern recipe, Elizabeth Raffald never went to Italy.
You're calling it sans evidence the result of a Grand Tour, which would've been centuries before its time to be recorded in the late 1300s.
