"Why does soup splatter all over the place when I puree it in the food processor? Am I doing something wrong?"
It isn’t that you are doing something wrong so much a there is a better way! Always work in batches when you puree soup or any hot liquid—don’t fill your work bowl more than about halfway to two-thirds. Also, if you have solids in your soup that you can place in the work bowl first, slowly add the liquid through the pour spout and keep your speed on low (if your machine has speeds).
