WHERE TO EAT The best Pizza carrettiera in the world (according to food experts)

"A hidden gem, Pizzeria Trianon Da Ciro is worth seeking out. Always filled with locals, Trianon spans three floors and serves up some of the tastiest flavour combinations in the city. Although also famed for its specials (for example, an Italian sausage pie topped with broccoli), Pizzeria Trianon Da Ciro is a great place to experience traditional pizza dishes too. Expect fresh buffalo mozzarella, beautifully cooked crusts and perfectly concocted sauces."

"So here is Pizza salsiccia e friarielli, with black Casertano pig sausage, zucchini pesto or Datterino tomatoes that perfectly match Agerola Fior di Latte, San Daniele aged 18 months and Grana Padano aged 24 months. All artfully seasoned with extra virgin olive oil."

"I love this small pizzeria in the Quartieri Spagnoli, where for a few euros you can enjoy a nice beer, and an excellent pizza, and here, I often choose the salsiccia e friarielli, which is truly indescribable goodness."

"The best historical pizzerias in Naples: Pizzeria Dal Presidente - The specialties are varied and all very tasty, from the simple to the Carrettiere pizza (mozzarella, friarielli, sausages, cheese). All pizzas prepared with traditional ingredients and wisely joined together."

"Every inch of wall space is covered with celebrity photos, press clippings, and napkin doodles preserved in picture frames. The homespun authenticity hasn’t made Da Attilio famous but it does keep it on the shortlists of some very respected pizza people. What to order - Broccoli Raab and Sausage."

"Salsiccia e friarielli at 3 unmissable addresses in Naples: Gino Sorbillo - The flour is organic with the mixture developed almost a year ago and continuously refined by Toto Sorbillo, world champion of traditional pizza, that will make you move."

"Where to eat them in Naples - at Pizzeria Concettina ai Tre Santi."

"The story, played by Salvatore Di Matteo, who makes a salsiccia e friarielli that respects all the classic rules."

"It is a reference for everyone, especially for the guys who have been doing the same job for a few years. A manual for salsiccia e friarielli."

"A couple of tables inside, and a little terrace outside, at which you can enjoy great pizza to the sounds of the thundering Corso Umberto traffic. The very large pizzas more than make up for the lack of ambiance. Delicious salsiccia e friarielli."
