This didn't gel for me. Boiling for 1 minute didn't seem long enough and i am sure that is why it didn't gel. If you make this recipe, boil until a candy thermometer reaches 220 or use the spoon test.
I too thought it didn't gel but this one takes 48 hours to set. Came out perfect.
I followed the recipe to the letter and it didn't gel.
This didn't gel, even though I followed the directions to a "T"
