The soup draws its main flavors from olive oil, cured meat, and watercress. It gains substance and supporting flavors from the peas and a little onion. The combination is delicious, warming, and celebratory in a rustic way. I like to serve with a bottle of Tabasco or any vinegar hot sauce at the table.
Frozen black-eyed peas (and white beans, chickpeas, and others) can be found in the supermarket freezer, and their convenience and quality are unparalleled; they’re faster and easier to use than dried beans or peas and far better tasting than canned ones. In the case of black-eyed peas, they need about half an hour to become fully tender. If you use precooked peas or those from a can (please rinse them first), that time will be reduced to almost nothing.
