On 2022-11-20 we had a post here, “Finally! U.S. National Standard Domestic Sludge”, about the U.S. National Institute of Standards and Technology’s catalogue of Standard Reference Materials. Well, suppose you wanted to make a Standard Reference Chocolate Chip Cookie? Some of the materials, such as wheat flour, dried eggs, and chocolate are available and others can be obtained a laboratory-grade chemical supplies. For a mere US$ 3000 or so, you can obtain enough to make one (count it—one) fairly large cookie.
But how does it taste?
