About Leigh-on-Sea Cockles

Traditionally sold with winkles and whelks, cockles have been a popular British seaside snack for many years. They were also sold outside London pubs by vendors who, in the absence of scales, used a pint glass as a measure. Cockles still grow naturally in several areas around the coast of Britain but these cockles are caught, cooked and sold by Osborne’s and are sourced from the Thames Estuary where they have been growing for centuries.

Handling frozen fish

Blast frozen fish, provided it’s cold to touch – so it hasn't got warm enough for bacteria to proliferate – is perfectly safe to re-freeze and will not affect its quality. That is industry standard practice.

Hence why we advise that if any purchase from our frozen range was to arrive partly defrosted it is perfectly okay to pop in the freezer to enjoy another day.
