A non-reactive bowl is a type of mixing bowl that is made from a material that does not react with food or ingredients. Non-reactive bowls are made from materials such as glass, ceramic, stainless steel, or plastic. These materials do not react with food acids like yeast, lemon juice, vinegar, or wine. Using a non-reactive bowl is important when making food that requires precise pH levels or that is sensitive to changes in taste or color. It is also beneficial for maintaining the quality of ingredients and preventing any unintended reactions that may affect the final result.
