I got the recipe at DL a several years ago and made it at home. (Not sure if it is the same recipe listed by previous poster.) It didn't taste right at all (and I am very good at following recipes).
I realized something this last trip to DL (the Mint Julep Bar outside was closed) we got Mint Juleps inside the French Market Restaurant - just really bad! Even the CM's there told us it would be. But the ones at Blue Bayou are wonderful! And the CM's at French Market told us they were different - they couldn't tell me why????
I don't know what the difference would be (and no, it wasn't the setting, I CAN tell the difference). We ate at Blue Bayou one day (great Juleps), had Juleps at French Market another day (shocked how bad they were), and then ate at Blue Bayou again and they were still wonderful.
The servers at Blue Bayou didn't seem to know what I was talking about when I mentioned the differences but the servers at French Market all agreed they aren't so great there and tried to warn us. We actually threw them away. Tasted like bad mouthwash.
Weird. Machines different? Ingredients? Person making the batches? Small or larger batches? I wish I knew what it was.
Good luck!
