12 months+Serve small, tender, well-cooked pieces, still chopped small.

Are cockles safe? Choking & prep

Shellfish is a top-9 allergen, so introduce cockles on its own and watch for a reaction over the next couple of days. Cook it thoroughly, never raw, to avoid foodborne illness, and remove all shell. Rinse cockles well to clear any grit, cook them fully open, and chop the soft meat small. Keep it plain and unsalted, and start with a small amount.
