This recipe has been in my family forever. My mom used to make it all the time here in the States and in Portugal. She learned it from my grandmother who learned it from her mother. And who knows how further back it goes. I know it's goes back more than 100 years. I grew up on this soup. It has a pleasing delicate flavor. Though my mom and ancestors have made it with rice and tiny pasta stars (found in Portuguese markets), I LOVE to use it with barley, so that is what the ingredients and method will list.
