The term "overmix" refers to a situation where someone or something is mixed too much, resulting in an excessive blending or combining. In cooking, overmixing can occur when a recipe calls for delicate folding of ingredients rather than vigorous stirring or beating. This can lead to tougher baked goods and a loss of texture. Overmixing is also used more broadly to refer to any situation where someone or something is combined too much, resulting in an over-processed or excessively blended outcome.
