It is better to use slices of bread.
Dry/stale bread toasts more quickly than fresh bread and thinly sliced bread toasts more quickly than thickly sliced bread.
You may need to adjust the browning control according to the thickness and freshness of the bread.
You can also toast bagels and your favourite breakfast bread types.
Some of our toasters have a bagel feature, which heats up to toast only the cut side of the bagel.
