Piquillo chillies are small, triangular peppers with a vibrant red color and a smooth, glossy skin. They have a mild heat level and a sweet, tangy flavor with subtle roasted notes, especially when fire-roasted — the traditional preparation in Spain. Known for their tender yet firm texture, Piquillo chillies are often stuffed, marinated, or served in tapas. Their appealing shape, rich flavor, and versatility make them a gourmet favorite in both home cooking and fine dining.
