I am making bagels using Peter Reinhart's formula from Apprentice. I have mixed the sponge. Q: Once I form the bagels and place them in the fridge to retard, would it be harmful/beneficial to have them remain in the fridge two nights instead of one? Would rather boil/bake later than I had initially planned. Thanks!
It should be mildly beneficial. That's one of the benefits of retardation - your scheduling can be more flexible.
