The recipe calls for the optional use of Xanthan gum powder, which is an emulsifying agent that will keep the ingredients well mixed after shaking a jar of the dressing. Xanthan gum has maximum effect the day after the dressing is made. You can buy Xanthan gum powder via the Internet at places like www.bulkfoods.com ... and it is inexpensive and useful in many recipes, including some for ice cream! Discussion of using hydrocolloid thickeners like Xanthan gum is one of the topics in the Food Nirvana Fundamentals Technology section. It is worth your time to take the time to read it.
