Is there a place in the LA or OC area that sells any of the chemicals used in Molecular Gastronomy? Stuff like Methylcellulose, Sodium Alginate, Calcium Chloride, Citric Acid, Gellan, Xanthan Gum, etc.
I know you can get all of these things online and I've done so in the past. I'd prefer to find an actual store for impulse and inspiration. Sometimes I put together crazy dinner parties on short notice and can't wait two weeks to get Xanthan Gum shipped.
