I made PERFECT fudge 2 wks ago. Used almond milk, margarine-yogurt, and marshmallow creme. This time, it is gooey. The flavor is good but I can taste little granules of sugar, and I have to keep the whole thing refrigerated. Even with-that, I can't cut it; I am just scooping it with- a spoon. Did I boil it to long? Possibly forget an ingredient? Add too much vanilla? Help!
