When I create my own recipe, I am never sure if I should bake it at 350 or 375 degrees. I have several cookie recipes that says to bake at 350 and others say to bake at 375. Is there a general rule of thumb as how to decide which to use?
Experimentation is the key in any recipe development, informed by the effect of the variable under investigation.
In baking cookies, the affect of the oven temperature will effect:
In most cookie recipes, the difference between 350 and 375 F may actually be smaller than other uncontrolled variables like the type of oven, individual oven variance, type of cookie sheet, size of individual cookies, and so. Additionally, within certain limits, there is a trade off between time and temperature.
For these reasons, you will need a high degree of consistency if you are doing dry runs to try to determine the optimal temperature.
