I have an oven that’s rated to reach 200 degrees C (around 400-ish in F) (I can’t put in higher temperatures on the device), but some recipes tell you to bake at higher temps than that. Does that mean that I can’t bake that item in my oven, or can I just adjust for time? Let’s say the recipe says to bake at 225 degrees C for 25 minutes, I then bake it for 35 minutes at 200?

Could you add a small wireless fan to circulate air and make better use of the heat you have? Sort of a DIY convection?

ETA- i love a good science fair project! Make some cookies or biscuits or something, like two at a time over and over, trying different methods! Report back!

That’s a fun idea :)
