HELP. I followed this to the letter--3 successive days (each was a messy failure). It was the same each time--watery brown milk. Read the recipe, as it says to whisk it-not use a mixer (don't believe that would make a difference). Maybe there's a misprint. I wanted it to turn out like the photo but it turned out like a bowl of milk/coffee and vanilla jello (after hours of refrigeration). ????? What happened? Anyone?
