Which utensil is commonly used to stir-fry ingredients in a wok?

The spatula is the most commonly used utensil for stir-frying in a wok due to its flat, wide surface, which allows for easy flipping and stirring of ingredients. This design is particularly effective in a wok, where high heat and quick movements are essential to achieving the desired texture and flavor of the food. The spatula can easily reach the curved sides of the wok, enabling cooks to thoroughly combine and evenly cook the ingredients without damaging them. This utensil also helps in scooping up food and serving once the stir-fry is complete, making it versatile for both cooking and serving.
