Pesto From the Sea

This vibrant seaweed-based sauce, known as Pesto from the Sea, offers a unique and savoury twist on the classic Italian condiment. By incorporating fresh kombu or wakame, this vegan recipe delivers a wonderful depth of umami flavour that perfectly complements the peppery bite of fresh rocket and aromatic basil. It is a brilliant way to introduce nutrient-dense sea vegetables into your diet while keeping the familiar, comforting textures of a traditional homemade pesto.

Naturally plant-based and gluten-free, this versatile green sauce is an excellent addition to your weekly meal prep. Serve it stirred through a bowl of hot linguine, drizzled over roasted seasonal vegetables, or spread generously onto toasted sourdough. The addition of roasted pine nuts provides a rich, buttery finish, making it a sophisticated yet healthy alternative to shop-bought varieties.
