A Chemical Engineer's Recipe for Chocolate Chip Cookies

Objective:Household cooking involves chemistry. Here is a cooking experiment in which the product is edible.


236.6 cm3 (500 mL) partially hydrogenated tallow triglyceride (butter or margarine)
177.45 cm3 (177 mL) crystalline sucrose (sugar)
177.45 cm3 (177 mL) unrefined sucrose (brown sugar)
4.9 cm3 (5 mL) 4-hydroxy-3-methoxybenzaldehyde (vanilla)
2 calcium carbonate-encapsulated avian albumen-coated protein (eggs)
532.35 cm3 (500 mL) gluten (flour)
4.9 cm3 (5 mL) sodium chloride (salt)
4.9 cm3 (5 mL) sodium bicarbonate (baking soda)
1 package of theobroma cacao (chocolate chips)
236.6 cm3 (250 mL) chopped de-encapsulated legume meats (nuts)
measuring spoons
measuring cups
mixing bowls
cookie sheets


Cream the partially hydrogenated tallow triglyceride, methyl ether of protocatechuic aldehyde, crystalline and unrefined sucrose in a bowl.
Add the calcium carbonate-encapsulated avian albumen-coated proteins and mix well.
In a separate bowl combine the gluten, sodium chloride, and sodium bicarbonate.
Add to creamed mixture.
Stir in theobroma cacao and de-encapsulated legume meats.
Place the final mixture piecemeal onto a cookie sheet.
Heat in an 463 K (190°C/ 375°F) oven for 8-10 minutes and allow the chemical reactions to take place.
Remove from oven and place on cooling rack.
