My first advice was quite negative, based on a purchase from a shop.
I have ordered the Focaccia directly from Crozzo, and there were no issues at all with the quality of the oil, the quality was very good.
I confirm the true Italian Focaccia is half the thickness, at least in the regions at the North of Italy, maybe in other regions is different. To eat this Focaccia you need to cut it with a knife before, but in Italy the Focaccia is eat in bites, no need of knifes, because is thin.
To exalt the taste, I suggest heating it in an Airfrier for 4 minutes.
However, it is very good and by sure it is the best Italian Focaccia you can found in Mumbai.
