Great video. I bake cookies ALOT especially during the holidays and I experience exactly what you state about prior to preheating and not waiting 10-15 minutes and then bake. I will definitely will preheat, wait 10-15 minutes and bake. THANK YOU! great tip!
I bought a new stove in Jan. It is elelctric and I am now finding I am unable to bake cookies as I have done for 50 years. My recipe takes 8-9 minutes per batch but my new oven has a temperature fluctuation of 50 degrees. It will reach 350 degrees and then it will drop to 300 degrees over the next 10 minutes and then quickly reheat to 350 degrees. The drop starts even if you do not open the oven door. So unless you are micromanaging your oven and have a digital probe inside you have absolutely no idea where your temp is when you put in a tray of cookies. SUGGESTIONS??
You didn't mention it in your video, but I presume oven cleanliness is a factor. I'm guessing the porcelain would have to be significantly dirty to have a noticeable effect. However, I suppose "it depends". Perhaps there are so many variables (temp, time, ingredients, etc.), that it would be a waste to state the obvious. Just clean your oven. Remove the potential effect.
We didn't think about that, that's something to consider for sure! But yes, it's good to just always keep your oven clean anyways!
