Culinary uses

Coat whole or fillets of herring in oatmeal and pan-fry for a quick breakfast or supper, with or without bacon. Herring is delicious when cooked by marinating it in pickling mixtures and serving with rye bread or potato salad. It can also be grilled or barbecued, and is good spread with Indian spice pastes.
