I made this soup to use up leftover black eye peas and potatoes.
Velvety starches from diced potatoes meld with dairy fats and earthy legumes, producing a broth that coats the back of a spoon with thermal efficiency. Soluble starches leach from the potato exterior during the 15-minute simmer, thickening the vegetable stock naturally without requiring added roux or slurry.
Freezing this soup requires caution because dairy fats separate and starches sponge up moisture during thawing. Store portions in airtight glass containers for up to three days in the refrigerator, reheating gently on the stovetop over low heat while stirring constantly to re-emulsify the fats.
