I made pepper jelly and had a bit of the yellow stuff at the top after canning. Thought it might be the butter that was added. However, as the days went on, I noticed more. As a former microbiologist....I just could not in good faith give this jelly so it went down the drain and the jars are clean for the next round of whatever fills them.
After our foray into making Christmas cookies yesterday, we made them a la my family recipe (we add orange zest to the recipe).
