An amber-coloured and strongly scented pesto with a sweet and sour flavour given by the caramelised onions, balanced by aromatic and slightly spicy notes. The Pecorino Romano cheese also contributes to making this pesto particularly tasty, adding a strong savoury note. The texture is enveloping, perfect for stuffing sandwiches, piadinas, bruschettas. Also ideal as a condiment for first courses and as an accompaniment for meat and side dishes.
