Karen, I had the same experience. Let me provide a flashback:
"During the Holiday Hell of 2004 I became addicted to making Gayle in MO’s chocolate fudge. Gayle is one of those people who have a natural affinity for making candy. I feel certain that if the Hubble camera zoom-lensed into her Missouri kitchen, we would find Gayle at the stove whipping up tins of fudge, standing on one foot with her hand tied behind her back.
But I am here to admit—in public—that unlike the 4,386 other posters who made her fudge recipe, I had no easy time of it. Not the first time, nor the second, nor the third time. The more I failed, the more I was determined to repeat the recipe until I succeeded. It is possible that my glucose level during that period left the realm of integer numbers and sailed right into the Imaginary range. The fourth attempt brought success and cathartic release. I was safe for another year."

Years later, when making lemon cream in the blender with the warning that the butter couldn't be added until the lemon egg base was below 140 degrees, I had the sudden thought that THAT might be the fudge problem I was having. That my melted chocolate was too hot (or the butter too room temperature) and that's why it didn't emulsify like Gayle's does.
Also, Gayle mentioned making lots of tins of this fudge and maybe her larger mass didn't get as hot as a single batch.
I blotted up the excess butter too which ended up making the fudge a bit crumbly. Folks still loved the taste, but I was disappointed with the texture of mine since I knew it should be silky and I'd screwed up.
