I am perplexed by this and would love some help troubleshooting it from those who are like minded. I have made my own mayo for about a year and I have never had a problem with it. I buy this lovely new Vitamix and I cannot get my mayo to turn out in it. I even tried the recipe in the book. The only thing I can think is that my house is pretty cool right now ~ maybe room temp is too cool? Any thoughts?
