The sapeur apron is linked to Lyon gastronomy in which tripe products play a major role.

This double-fat dish owes its name to Maréchal de Castellane (military governor of Lyon under Napoleon III), a fine gourmet and lover of trippes, but also a former engineer.

This dish would therefore take its name from the leather apron worn by the sappers to carry out their work.
