Eddy,I did preheat oven, one sheet in the middle rack, the other right under it to the side of it and after 6 minutes I switched them. That’s what
I do with Biscoitos. After 12 min. I looked though glass door of even and neither of them had started to brown..After 20 min. It did but were hard as rocks...Oh well.Think I will stick to Biscoitos they always come out for me..no worries. Keep them coming you and your wife are doing a great job posting them, especially for us that remember most of these recipes from childhood!! God bless you both..
