Cultural Tip
French cuisine places a strong emphasis on technique and equipment. Because French ovens (especially older wood‑fired or convection models) can behave differently, many classic recipes include the phrase ‘ajuste en fonction de ton four’ to remind home cooks to calibrate the heat. In a professional kitchen the instruction would be more precise, but at home it invites flexibility.
