As long as it takes to get the real thing back. Challenges are a good thing if it wasn't for blog such as this the importance of this product would have never been taken to this level, and the most important thing is the way myself and others here have learned to make a copycat version of a great sauce as a matter of fact I have come up with a few other recipes while trial and error of the copycat. Just keep cookin folks its becoming a dieing art !
Thanks Neil
