I think the mini or first frame will take about 25 to 30 minutes.
Keep the temperature the same and I'll tell you how to check the baking time.
First, after baking for 18 minutes, more than half of the roasting color would have turned light brown. Turn the oven around and add about 7 minutes. If the roasting color is too thick, the top surface will be excited, so if the roasting color is similar to the color from the lecture, please take it out.
If it's too light, please add one to two more minutes.
It may vary depending on the oven, so you should check the baking color with your eyes. :)
If you check the baking time and write it down in the recipe in the attached file, it's a customized recipe for you!
Please grill it well in a small size and share the pictures.🙂
