1.24.42 The really interesting thing there is because browning occurs best in outlinedenvironment and amino acid molecule like those fan and flour have two ends. They have amino end and acid end. And in acid end it is a synthetic and amino end is outlined. Its outlined has to react with sugar molecules. For the Millard action and the browning to occur. And in the synthetic dough, the outlined deactivated but in the outlined dough, something make alcohol more addition of baking soda, the amino acid dry and the react with sugar to create browning.
1.25.27 Baking soda also occurs its spread. It rises the Ph of the dough and sort of weaken the gluten development. So, the more spreadyou get in the cookies, the chewy it’s going to be. If the dough don’t spread very much, they end up baking up so tall and more cakey rather than chewier.
1.25.49 The other variable, in term of ingredient, beside leveners would be the yolk, and we’re using the yolk rather the whole egg and the type of the amount of flour. We got rid of the egg whites because it kind of gain createmore structure and more cakeyness, one of the fat from the yolk and we didn’t necessarily want the structure from the protein in the whites.
1.26.16 So in addition that we re-engineering the ingredients of this, I just wanna come back to couple of sort of variable we talked about in the beginning. We used a couple of techniques in the recipe. So here’s an example of us putting in a tray of cookies and leaving them be. And if you notice, cookies in the back are browner than cookies in the front. That’s because oven has hot and cold spot. So every single cookie recipes that we’ve ever developed in American Test’s Kitchen, we switch the position of the baking sheet to 180 degrees. So half way through, front becomes the back, back becomes the front.
