On the hills around Caiazzo, in the province of Caserta, the olive called Caiazzara is a variety spread through that landscape. When it ripens, an intense wine-red colouring runs through the flesh as far as the stone, so the fruit looks complete rather than merely stained on the skin.
Those traditional olives are prepared by baking. They are passed through the oven so they dry quickly and the flavour turns more concentrated, a small act of heat that trades water for depth without adding other ingredients.
Dressed with oil, fennel and hot chilli, they form a lively antipasto and sit well beside local pecorino. That pairing is the practical cue to carry forward: look for the same hill fruit when you next meet Campania’s table olives, rather than treating every dark olive as interchangeable.
