Hello. Been enjoying some Brie I bought at Costco. Kirkland brand and very good.
Well, I guess I didn’t eat it fast enough, and now it is very strong. So strong that it is no longer desirable. I hate to toss out food. Is there anyway to resurrect the Brie? So, it is palatable once again?
If it smells like ammonia, there’s no way to fix it. 
If the flavor has just become too sharp, mix it with something sweet like pepper jelly or brown sugar.
Cutting off the “crust” will help mellow the flavor a little.
Other than that, what MadMonk says is good advice. Sweet flavors help offset the sharpness. If you’ve ever tried baked brie, that’s a good use: put a few spoonfuls of your favorite jam or marmalade on top and wrap in puff pastry. Bake until crispy outside and gooey inside. (Warning: I take no responsibility for what this recipe does to your waistline.)
