Now there are recipes on Youtube and ones that I make too, where you just add the oil all at once, but for this one... I prefer to almost dribble the oil in... which looks like a pain - but it pays off with a more commercial-like dressing results. Note: Xanthan is optional and NOT as necessary if you whisk the oil in slowly enough.
However, adding 1/8 tsp xanthan gum (love it!) option... Mind you, it's a very POWERFUL thickener...
SO just a little bit DOES GO A LOOOONG WAY
You can find little inexpensive packets at Walmart Stores, ours sells them on the baking aisle where they have Gluten-Free items, near the sugar and spices. Q. You might ask, "If xanthan gum is NOT necessary, then why even list it?" A. The 1/8 tsp just makes the recipe a little less goof-proof, (yet don't be goofy) by adding a lot more!
Make dressing a day ahead first by processing* - blending the ingredients - without the oil, until the sugar dissolves. Then slowly hand whisk in the oil until dressing reaches the desired consistency. Refrigerate. Shake bottle before drizzling over salad greens, marinated & grilled chicken and desired toppings. Note: *May substitute 2 tsp fresh ginger or 1/4 tsp. ground ginger for HOMEMADE SWEET GINGER, however instead with it... it's sooo much better. In fact, all my recipes with fresh ginger are!
