Abstract -
Kingsley and I wanted to do a project on cookies. We wanted to know if refrigerated cookie dough is better than non-refrigerated cookie dough. We bought ingredients for the two sets of cookie dough. We made the first set and place it in the refrigerator for forty-eight hours. After forty-eight hours, we made the second set and start baking cookies. We got ten people to try the cookies and pick which is the best cookie. We found out that refrigerated cookie dough makes better cookies than non-refrigerated cookie dough.

PROBLEM

Purpose -

Most cookie recipes call for all-purpose flour. A very few require cake flour or bread flour; however, sometimes you need to work with what you have on hand. Understanding how to substitute bread flour and the likely result when you're baking cookies can help you make a successful substitution and a delicious batch of cookies.


History -
Chocolate Chip Cookies were invented in 1937 by Ruth Graves Wakefield (Stradley). Believe it or not, the chocolate chip cookies were made by accident! Ruth wanted to make her favorite recipe, "Butter Drop Do" cookies, that required baker's chocolate. She didn't have any, but she had a bar of semi-sweet chocolate. She chopped it up and stirred the chunks of chocolate in the cookie dough. Ruth assumed that the chocolate will melt and spread through out the cookie, but instead the chocolate stayed its shape. She named the cookie, "Toll House Crunch". Later, it was named "Chocolate Chip Cookie".

A long time ago, people used snow and ice, cool streams, springs, caves, and cellars to refrigerate food. Fish and meat were preserved in warm weather by salting or smoking. Egyptians and Indians made ice on cold nights by setting water out in earthenware pots and keeping the pots wet. Two of the first home refrigerators appeared in Fort Wayne, Indiana in 1911. It began to get popular and now the refrigerator is used in more than 99.5% of households. (The History of the Refrigerator)

Applications -
Do bakers refrigerate anything else before baking? research.

Hypothesis -
If cookie dough is placed inside the refrigerator for 48 hours, then the cookies will taste better than the cookies that aren't refrigerated.
