Laver

Laver is a group of thin, sheet-like red seaweeds (Porphyra species) found along coastlines worldwide. It is best known as the seaweed used to make nori — the dried sheets that wrap sushi — though in its fresh or minimally processed form it has a softer, more delicate texture and a sweet, umami-rich flavour.

In Welsh and Irish cooking, laver has a long tradition — laverbread (bara lawr) is made by boiling the seaweed into a dark, paste-like purée that is rolled in oatmeal and fried. In East Asian cuisines, it is dried into sheets or flakes and used as a seasoning, wrap, or snack.

Fresh laver is occasionally found at specialist fishmongers and Asian grocers in Australia, while dried forms — nori sheets, seaweed flakes, and roasted seaweed snacks — are widely available in supermarkets.

How it's made

Laver is harvested from rocks along the shoreline at low tide, either gathered wild by hand or cultivated on nets and frames in shallow coastal waters. The thin, slippery fronds are washed thoroughly to remove sand and salt, then either sold fresh or processed further — typically dried into flat sheets (as for nori) by spreading the seaweed onto frames and drying it in controlled conditions. Some preparations involve chopping and slow-cooking the seaweed into a soft purée.
