How many times have you plated a beautiful serving of pasta, only to end up with a red, watery pool on the outside of your plate? It's not very appetizing, right? It also ruins any Insta-worthy plate pictures you were hoping for once dinner is served. That watery mess is what happens when the water in your pasta separates from the oil in your sauce, and an emulsifier stops that from happening. It helps the two to combine and hold together, thickening your sauce to smooth deliciousness.
