Answer:
Heterogeneity
Explanation:
Heterogeneity is defined as a characteristic of a material that is not uniform in various characteristics such as colour, height, taste, shape, distribution, weight, and so on.
On the other hand homogeneity is when different samples of something are consistently the same.
Hannah has been used to the homogeneity of the previous chef's cooking. So when a new chef was brought in to cook due to heterogeneity she felt the lasagna she was served was undercooked and starkly different in flavor compared with the ones she had previously eaten at the restaurant.
