The ancestral West African street shellfish — tiny marine snails boiled with pepper, extracted from the shell with a pin. Dense in protein and zinc.
Periwinkle is sold in cups on street corners in Lagos — the street food of the coast. For West African diaspora communities, particularly those from coastal states (Bayelsa, Rivers, Cross River, Akwa Ibom), periwinkle is a taste of the coast and the childhood.
Periwinkles (like all shellfish) are extraordinarily nutrient-dense. Zinc content rivals oysters — critical for immune function, wound healing, testosterone production, taste and smell. B12 content is high — addressing the B12 deficiency common in plant-forward diets. Iodine supports thyroid function. The small serving size means high nutrient density with very low caloric cost. In West African coastal communities, periwinkle served as the high-nutrient protein available to those who could not afford larger meat — ancestral evidence of its nutritional role in food access.
Purchase fresh or frozen periwinkles at African grocery stores. Boil with salt, pepper, seasoning for 10-15 minutes. Extract meat from shell with a pin. Add to soups — edikaikong, pepper soup, egusi. Can also be stir-fried.
