Evaluate the following scenario and critically think about the following statement: "Chemistry is like cooking"

Last night I made a large pot of soup. I added the following ingredients into a pot:

[Potatoes, green beans, onion, celery, carrots, chicken, sazon, adobo, rice]

I added some heat into this pot and let it simmer for about 30 minutes. After I finished cooking the soup, I went ahead and served myself a large portion. To my surprise, when I was eating the soup, I found that there was beef and noodles in the soup?!

1. Is this scenario possible?

2. Does this equation make sense?

[Ingredients for chicken and rice soup] yield [beef and noodle soup]

3. In chemistry, do my ingredients need to match the results?
