Flour question

[3goodeggs]

I bought flour in bulk. I then divided it up and froze what I did not think I would be using quickly. I forgot to label one container. Is there anyway to tell the difference between bread flour and all purpose?
I have made bread with all purpose before and it was okay, but if this is bread flour, will I ruin a perfectly good pound cake with it? Are pound cakes heavy enough to forgive the extra gluten?
I know you all will know how to help me.

I may just use it all for bread.
Old age is harder than I thought it would be!! The mind is the first to go.

(Really,...it was the figure, but the mind is is a close second.)

I know that self-rising will have a "taste" to it because of the baking powder added to it - not sure if bread flour has a taste. Worth a try.

I can not taste a difference. I appear to be gluten intolerant... so...I guess I could eat some....but I'd rather not.
I may just make a small loaf and a small cake and see which turns out better. However, when you have a teenager-It is all edible. quality seems to mean nothing.
