Make potions, make money, no problem! 

Use the mouse to drag materials from the side rack into one of the circles on the table.  Once you believe you have the proper mixture make the brew in the middle.  

The order for the potion is at the top.  It can be a variety of things but unfortunately we don't  don't have a recipe book so take a guess and good luck, what could go wrong. 

The better your potion is the more money you will make, but if you make a bad one you might lose all or some of that sweet gold.
