If you have not kept records, it would be very difficult to know which recipe hadn't been completed and needs to be "redone". You might have to start over and systematically redo each recipe, which I did in one of my games and was thrilled when the award actually showed up.
to get that award do you have to make 50 diffrent recipes or can you just keep making the same one over and over again?
For goodnes sakes, man, you didn't even have to read the last thread; the most recent post (at the time of your posting) contained the answer, and you don't even have to go to a second page to view it.
This is why we have 60-post threads about simple questions; the same question is asked over and over, and the same answer given over and over, until a simple question like "How do I keep the shark potion from exploding" turns into a 60-post thread.
