I add a little bit to cold soups/juices in the Vitamix, that might separate, when I chill them. It doesn't take much - only 1/4 tsp to a qt or so, maybe a little more for really watery things, like cucumbers, and if I've added yogurt. I open the top, and get the VM running fast enough to form a vortex, then slowly add the XG to this. Then, I put the plug back into the top, and increase the speed to high, and it thickens quickly.
