What is a Toaster? Everything you need to know. - Cooking Indoor

Learning with Lyrics! on Instagram: "How come a toaster know not to burn the second slice? 🧐🍞 A toaster doesn't burn the next slice because the bimetallic strip doesn't turn off until the toast is done, and it uses an initial heat-up period to toast the first slice to the desired level. When a second slice is toasted immediately, the toaster starts at a higher temperature than it does from a cold start, making the second slice toast faster and sometimes causing it to be darker than the first!
