Sea Lettuce: Vibrant Greens from the Tide

Description

Sea Lettuce (Ulva lactuca) is a bright green algae that resembles its terrestrial namesake, lettuce, but with a translucent, silky texture. It brings the fresh, bracing essence of the ocean to the plate. Found in intertidal zones globally, it is accessible and versatile.

Its flavour is strongly marine—salty, grassy, and slightly peppery. It is incredibly light in calories but dense in nutrients, offering a spectrum of minerals including iron, calcium, and magnesium, alongside Vitamins A and C.

Culinary Uses

Sea lettuce can be enjoyed raw, dried, or cooked. Its delicate leaves are perfect for adding colour and a savoury hit to dishes without overwhelming them.

• Salads: Use fresh or rehydrated leaves to add a vibrant green hue and salty kick to mixed salads.
• Soups: Float in clear broths for a beautiful visual and mineral enrichment.
• Seasoning: Dried and flaked, it becomes a nutritious sprinkle for rice, potatoes, or eggs.

Health Benefits

Sea lettuce is a fantastic dietary addition for detoxification and immune support. Its antioxidants combat oxidative stress, whilst its iron content combats fatigue. Like other seaweeds, it is a good source of iodine for thyroid health.

As a fast-growing, nitrogen-absorbing plant, sea lettuce is a sustainable choice that supports cleaner oceans while nourishing the body.
