"Neo's Noodle Soup" In a large pot over medium heat, melt butter. Cook onion and celery in butter until just tender, 5 minutes. Pour in chicken and vegetable broths and stir in chicken, noodles, carrots, basil, oregano, salt and pepper. Bring to a boil, then reduce heat and simmer 20 minutes before serving. There is no spoon.

This cookbook was insightful in the sense that I once tried proving several of its identities via Kronecker products but then found that it was much easier using tensor notation, so easy that I almost forgot Kronecker products altogether. I put together some proofs in my blog [0] (note: it's incomplete and the URL might change!). [0] https://mbustamanter.github.io/ssg-blog/2022/matder1/
