They're useful for more than pizza. I remember on one of my trips to Italy our hosts had one inside their home in the kitchen and at their "mountain house" they had one outdoors and they put EVERYTHING in those ovens (ribs, steak, roasts you name it)
and
This was at their mountain house. The guys were our hosts. The younger guy "Bruno" is the dad of one of the exchange students we hosted over the years, the older "Luigi" (you know I can't make this stuff up LOL) is her maternal grandfather. We were at the mountain house in the Alpi Orobi region northeast of Brescia Italy. The photo with them smiling at me, was purely candid. I had walked up to them and simply shouted "hey Bruno eh Luigi" and they turned and smiled. The end result was a priceless photo. Inside that oven was more kinds of delicious meats (ribs, sausages, roasts, chicken you name it) but oddly enough no pizza LOL.
The meat was basted with a delightful chimi churi made with parsley, garlic, chili flakes, EVOO, salt, pepper, a hint of vinegar IIRC anyway as those meats cooked racks were pulled out and basted occasionally and we sat outdoors at a table the size of an aircraft carrier on a covered ceramic tile patio. I think about 25 to 30 people in all. Much wine, laughter, and food flowed for hours and hours well into the night. Espresso, grapa, cheeses and fruits followed. It was pretty close to midnight before we left that table to sleep. The next day it started all over again!
Sorry for the long winded post. But seeing this brought a flood of wonderful memories
