I'd like to try making a pina colada bread pudding. The recipe calls for 1 loaf of French bread with crusts removed. Doesn't French bread come in different sizes? And aren't they rather slender so what would I be left with after I remove the crusts? How many ounces/pounds of bread do you think I should buy? The recipe calls for 3 eggs and about 3 cups of liquid. Thanks for any help provided.
