An olive, a chili, an anchovy, and a toothpick: that's all you need to make a "gilda," the classic "pintxo" from the city of San Sebastian in Gipuzkoa—home of these Spanish snacks. Some say that it originated in Casa Vallés, others in Bar Martínez, but both are bars in San Sebastian. On one thing, however, everyone agrees: that it was named in tribute to the actress Rita Hayworth, who played the title character in the film "Gilda," because it's "green, salty, and a bit spicy."
