i was cooking some dessert today which contains milk as a primary ingredient. While cooking I started to notice that powder ingredients weren't dissolving in the milk. After a while under heat they dissolved, but I noticed what looked like soap bubbles. We usually use Fairy Soap for washing kitchen tools and Clorox. Now I'm concerned if we can eat what I've made or if it poisoned. The soap came out of the tool I was using to cook the dessert. 
Best used is a date after which the manufacturer says quality will likely be reduced, not a spoilage date.  Most items are safe after that date though some jurisdictions restrict selling after that date, but not using.  That said, you are two years beyond that date.  At two years, if in need and seals look good, no container damage, no discoloration, no gases, no off smells, no other signs of concern, then maybe it would be worth a risk.  Your item does not fit that criteria in my opinion.  The odds of it being bad are actually low, buy what need to you have to run that risk at all?
