Cattle fat solidifies easily and is not suitable for cooking. Cattle fat can be used as the bottom material of hot pot. After cooking, it will solidify piece by piece, which is convenient to carry.
At present, many hot pot bottom materials in Sichuan cut corners and use vegetable oil instead of beef fat oil, but vegetable oil cannot be solidified, so paraffin is added for solidification. Don't eat this kind of bottom material.
