Final answer:
The provided excerpts do not explicitly mention Harriet and Carrie or their actions regarding their mixtures. To provide a factually accurate answer, more context is required from the specific text in question.
Step-by-step explanation:
The excerpts provided do not give a clear indication of Harriet and Carrie's actions with their mixtures after deciding not to eat them. This seems to be a test of comprehension and requires context from a specific text, likely a novel or play. Instead, various characters like Mrs. Peters, Louisa, Joe Dagget, and others depict reactions and relationships to food, objects, and situations, revealing themes such as gender roles and the intricacies of human behavior. The question may pertain to a particular story within these excerpts, but without a specific reference to Harriet and Carrie, it is difficult to provide an accurate response.
