THE BEST COOKIES !

-INTRODUCTION && PURPOSE
Have you ever bitten in to a cookie and thought, "this is the best cookie in the whole wide world!"? Was it homemade? Store bought? Everyone has a favorite cookie. Some prefer chocolate-chip, peanut butter, others prefer oatmeal raisin. Whatever your favorite type of cookie is, you're probably always wanting batch after batch. In this science fair project, you can continue your quest for the "best" cookie by seeing if a small change in your cookie recipe changes the flavor. -HYPOTHESIS && QUESTION

* What is the effect on the taste of cookies by the amount of refrigeration time? * If we change the amount of refrigeration time on the cookies dough then the results cookies will taste better to more people because all the ingredients have had time to set in and “ marinate “ CONCLUSION :

My hypothesis was that by changing the refrigeration time on the cookie dough the resulting cookies tasted better then cookies that were baked immediately after mixing the dough. My results do support my hypothesis, if you put a warm, melty dough into the oven, your cookies will spread before they begin to set up, they'll run into each other, becoming a single crisp, crunchy mess, the cooler the dough when it goes into the oven, the less it will spread, and letting the dough rest in the refrigerator for at least a day does wonders for relaxing the gluten, gives the flour more time to absorb the liquid This allows the dough to become drier and firmer making cookies that are soft and fluffy, which makes it taste better.
