The expiration dates from manufacturers are generally a "best if used by" type date, as there is no law governing how they are used. The manufacturer uses their own judgment. The best way to tell is by smelling it, if it smells bad, don't use it. If it smells ok, then taste it, if it tastes fine, then it is ok to use. Butter lasts a lot longer than the expiration date, I can attest to this. I have butter that has an expiration date from earlier this year and it is fine, it's all about whether you kept it cold enough. If butter is bad, it will have a sour taste or visible mold.
perfectly fine to use it
I would never use expired dairy products. That can't be good...
Kevin, one word three syllables, "yes".
Since it were in the refrigerator it should be safe, but it won't taste nice.
i thought that with cookies you used margarine? anyway, you could use it if it looks and smells okay. however if it smells not like butter should, throw it out.
NOO YOU CANT!
WOULD YOU EAT EXPIRED BUTTER ON YOUR BREAD ,?
THEN DONT USE IT , THROW IT IN THE BIT AND RUN TO THE SHOP AND GET A NEW ONE!
Smell it and taste a little - if it seems ok, it is fine to bake with. I have had butter go bad once - trust me, you'll know if it's bad! Expiration dates on dairy products/eggs/etc. really seem rather arbitrary, probably the earliest possible point the product would lose quality if stored under less than ideal conditions. But loss of "quality" does not mean bad for you. I used to cook in a soup kitchen and we routinely received donations of "expired" dairy items which were perfectly good, healthy and usable.
