Thanks all for the suggestions and recipes.

I cooked the fudge for the correct amount of time but I have a larger sauce
pan than what was suggested, perhaps the additional surface area caused more
evaporation. Also, the kit came with what looked to be lower quality
marshmallows than what I would normally buy at the store. IIRC the recipe
called for 2 tablespoons of unsalted butter. The fudge wasn't bad, but it
just isn't near as good as I was hoping for, I think it's lasted 2 or 3
weeks now, had it been better it wouldn't have lasted 2-3 days.

Thanks again for the recipes and suggestions, I plan to try some of them out
in the future when I make fudge.

My favorite fudge growing up came from the State Fair from Sam the candy man
that had a slab of marble that the fudge was made on. The recorded sales
pitch said he used real cream and real butter. Sure made good fudge, I
tried Alton Brown's recipe with cream and butter but it came out grainy,
maybe I accidently got crystals started too soon somehow.
