Ok... this is my third batch. I opened my can of liquid extract and found that some of it around the top had taken on a milky, foamy texture instead of the thick, dark syrup that I had my first two times. When I mixed it with water, the foam floated. It kind of reminded me of the spray foam insulation (Great Stuff) from the hardware store in color and texture. I'm currently boiling it... and it seems to be breaking down, but, last time I looked, there were still little white flecks swimming around in the pot. Normal? Not normal? Not going to be an issue?
