Which of the following indicates the batter needs to be changed?

The indicator that the batter needs to be changed is when the crust becomes flaky and brittle. This texture change signifies that the quality of the batter has deteriorated, which could affect the overall taste and appearance of the food being prepared. A flaky and brittle crust may indicate that the batter is overused or has been subjected to conditions that compromise its integrity, such as prolonged exposure to heat or repeated frying.

While odor, discoloration, and thickness are also important factors to monitor when assessing batter freshness, they do not specifically denote that the crust has lost its desirable characteristics. A fresh batter should maintain a smooth and even texture, ensuring that the food product has a consistent and appealing denseness. Recognition of these signs is crucial for maintaining high standards in food preparation and ensuring customer satisfaction.
