Tortellini

Unlike plain pasta, tortellini is stuffed — and those fillings are typically where the histamine concern lives.

• Aged cheese fillings — traditional tortellini often combines ricotta with aged Parmesan or Pecorino, which are high-histamine cheeses; even "ricotta-based" versions frequently include aged cheese in the mix

• Cured meat additions — prosciutto or similar cured meats in the filling add another layer, as cured and processed meats are among the more consistently high-histamine foods

Truly low-histamine tortellini would need a filling made entirely from fresh cheese (like ricotta alone) without any aged cheese or cured meat — worth checking labels carefully, as most store-bought versions include Parmesan.
