A repeated meal can connect generations while its ingredients change around their needs.

Continuity lives in the practice rather than in the recipe. A dish made every year can lose an ingredient to allergy, cost, availability, or somebody’s new diet and still do exactly what it was doing, which is putting the same people round the same table. Insisting on the original version can end a tradition in the name of preserving it. Adaptation is how a custom survives contact with real bodies.

Ask before the next gathering what people can actually eat. Change the recipe rather than the occasion, and mention the substitution without apology.
