halacha - What to do when uncertain regarding a Bracha on dessert during a bread meal?

If you are having a bread-meal and you have dessert in front of you, but you are uncertain if the homotzie covered it - what do you do?

Don't eat it? Eat it without a Bracha? Say shehakol (in the case that you don't know what the bracha is) and eat it? Some other option?
