I just did this yesterday - Made my homemade BBQ sauce (which my family and everyone we know loves), sterilized a jar, and water-bath canned it for 25 minutes.
However, I now have concerns about it...My sauce contains a little butter (about 1 Tbsp butter to 4 cups of sauce, butter is used to saute onions at the beginning of cooking).
All the recipes I can find online for CANNING BBQ sauce contain NO butter, or oil.
My one jar that I water-bath canned looks beautiful, with no bubbles, and it created a tight seal.
What are the chances that it won't be safe, if stored in my pantry? Does anyone know about this kind of thing?
Thanks for any help!
