You are spot on. I am a huge math nerd and I love to bake. Chocolate chip cookies are delicious.
After college I thought briefly about starting a cookie business. I have a notebook full of detailed cookie experiments. I changed quantities, ingredients, mixing technique, and baking temp/time trying to make the best cookies. My housemates tested the experiment results. Luckily, they were more than pleased most of the time.
Baking is all about chemistry and reactions. The delicious part is just a fantastic side effect.
Engineering is just using quantities, directions, and properties to effect a result.
