This week on Cooking Issues with Dave Arnold & Nastassia Lopez, learn why your spherification process may be going awry and how you can ensure your liquids turn into perfect spheres. Also hear why Dave prefers Ultra-Sperse over Ultra Tex and how one might make vinegar from Sherry. Later, find out why Dave is such a Jesus Christ Superstar junkie and what makes the original Judas irreplaceable. This program was sponsored by Modernist Pantry.

"The problem with Ultra-Tex is that because it's been pre-hydrated and pre-cooked, when you add it to liquids it tends to glob up the same way if you'd add starch to hot gravy. I recommend going with Ultra-Sperse instead of Ultra-Tex."
