The method for making French toast introduced on a television cooking show wasted the leftover egg mixture. Instead of 1 slice of bread, I used 2, which was just the right amount.
I used 2 slices of bread, instead of 1, as per the recipe from a TV cooking show, and it turned out to be just the right amount.
If you use 5-slice loaf bread (2.4-cm thick slices), there will not be enough egg mixture. I tried it, but the result was met with disapproval.
