Italian sausage

Preparation

Pre-cooked and crumbled or sliced before topping to render excess fat and ensure it is fully cooked

Best pre-cooked to control both doneness and fat release

Applied before baking.

Cautions

• raw sausage releases excess grease and may undercook in a short bake

History and cultural context

Despite its name, the fennel- or anise-seasoned pork sausage sold and used on pizza across North America as 'Italian sausage' is itself a North American product developed by Italian immigrant communities, not a direct import of any single sausage made in Italy — Italy itself produces a wide variety of regional salsicce that differ meaningfully from the American product, and some Italian expatriates specifically note fennel as a distinctly American addition rather than a shared Old World seasoning.

Traditional regions: United States

A standard topping on American-style pizza, sold in hot, sweet, and mild varieties, typically crumbled or sliced into coins before baking.

What it brings to a pizza

Moderate. Crumbled pieces season the bites they land in, but they lack the cured salt and spread-out fat of pepperoni, so the rest of the pizza stays itself.

Ordinal levels, not measurements. Salt, fat, water and the basic tastes come from this ingredient’s profile above; the rest is a strong culinary inference unless marked otherwise. Anything not listed is not assessed. Aroma: cured and cooked meat, spice and chilli.

Where it goes: on top of the cheese, before the bake (or under the cheese) — lets it brown; lets its fat render and the edges crisp. On thin pizzas, crumbles on top brown and crisp at their edges; under the cheese they stay moister. In Chicago deep dish a pressed layer of sausage goes over the cheese and under the sauce, where it cooks through without drying.

'Sweet' sausage relies on fennel and garlic; 'hot' versions add chilli flakes, which shifts it towards a heat source.
