Having researched many recipes for this condiment, it seems most of them have basic components of smokiness, heat, nuts, red peppers, tomatoes, olive oil and sherry vinegar. They also often include bread as a thickener, but mine does not. In fact, my recipe is so very simple I wonder if it is truly a Romesco sauce. I never measure the amount of nuts, olive oil, or sherry vinegar so the amounts below are approximate. Goes well with grilled fish, chicken, or meat or use as a dip for bread or veggies. A food processor makes this come together easily. I guess it is possible to make something more complicated by not using ingredients that are already processed, like the Smokehouse Almonds, jarred roasted red peppers, or canned tomatoes. But this works well consistently and friends always enjoy it. A very good quality Sherry Vinegar can add a nice touch, but I usually use what I find at the store, Big Lots, or TJ Max. Spanish chef, Penelope Casas, recommends Pimenton De le Vera for paprika.
