What common preparation mistake made with shellfish violates the carnivore restriction?

Answer

Coating them in breadcrumbs.

Adherents must ensure shellfish is prepared simply, ideally boiled or pan-fried using only animal fat like tallow or butter. Preparation methods that involve coating the food in prohibited plant-derived ingredients, such as breadcrumbs which often contain wheat flour, or deep-frying them in seed oils, immediately violate the diet's core rule against consuming non-animal matter and hidden carbohydrates.
