From a local source. I did some research on Catalonian cuisine to aid me with this recipe and inserted a few Pacific Northwest and Mexican ingredients, too. My many notes are in parenthesis below. Use the best quality ingredients-please. "How to use and serve: Packed in a glass jar or small bowl, Romesco makes a very nice hostess gift. You can use it as a spread for toasted bread; you can toss it with pasta; spread it in a sandwich; fill an omelet along with some goat cheese; or put a dollop on top of scrambled eggs or baked fish. Mix it in with smashed baby potatoes. Use it as a dip with vegetables. Or just eat it with a spoon."
