I have a convection toaster oven and a slot toaster. The slot toaster makes better toast faster. The toaster oven is for not heating up the house as much as the regular oven and not using gas appliances on days I can’t open the windows.

Extra buttery twice toasted toast:

Toast bread in slot toaster

Butter generously

Toast buttered toast in toaster oven (on a plate)

Allow to cool enough that second buttering will not melt completely

Butter again

Enjoy!
