I'm trying to make a soup recipe from the Chez Panisse Cooking cookbook, and it calls for "pimientos" it describes as red, heart-shaped, and sweet but with a little bite. anyone got a clue what these are?
They are large sweet heart-shaped red peppers. Sometimes they are canned. You can substitute pimento with large red bell peppers.
Probably too late for your recipe - but for what it's worth, pimentos are available from Goya in small jars. The jars usually contain two pimentoes...which do very closely resemble in look & flavor, skinned red bell peppers...
