"Cooking by the Numbers" is a recurring Sesame Street segment from Season 30.

Ruthie portrays Chef Rutheé, a Julia Child-sounding chef whose unusual recipes always result in numerals. When the announcer refers to her as "Chef Ruthie," she is insistent that the name is pronounced "Ruth–AY" instead. The segments follow the same pattern, with the chef using that quantity of ingredients to make a number.
