Wikipedia: Alphabet pasta
Alphabet pasta, also referred to as alfabeto and alphabetti spaghetti in the UK, is a pasta that has been mechanically cut or pressed into the letters of the alphabet. It is often served in an alphabet soup, sold in a can of condensed broth. Another variation, Alphagetti, consists of letter-shaped pasta in a marinara or spaghetti sauce.

It is not clear who invented alphabet soup, or when.

Just 25 days before the National Spelling Bee, reigning 2018 champion Karthik Nemmani tests positive for alphabet soup. What a shame.
