I had a former cousin in law who ALWAYS made fudge, but she NEVER
made it on a cloudy day as she claimed it always came out grainy if she
did.
Personally I don't know if that was just her way of getting out of making
it during the holidays this was in NC.
I haven't made it in YEARS myself I follow the recipe of one of the products
just can't remember which one it was the cocoa, condensed milk can or the
marshmallow fluff stuff.
Since I became diabetic (9 years ago) I haven't made the fudge.
