I am hoping that someone here is familiar with using the Amish
Friendship Bread Starter to make the cake-like breads. My question
comes about because at the beginning of the Starter use instruction
there is warning to not use metal dishes or metal utensils.

I imagine there may be reason during the ten day process of "mushing"
the starter for five, adding the milk, flour and sugar on day six,
mushing more days to then add milk, flour and sugar again on day ten
to remove four starters. But what about this tenth day of adding all
the other ingredients to bake just "your own" two loaves? Is it okay
to use my KA Mixer's metal bowl and flat blade at that point, being
only for two loaves immediately baked?
