What can I use to substitute propynel glycol alginate for the gruyere spheres? or where can I buy it, I have been looking in internet and I haven't been able to find it.
Gabe Quiroz, its wonderful that you work at EL BULLI, I just start trying to do some spherification with Texturas products an have some questions: which superbag do they use to strain the olives 100, 250, 400 microns?, for the minimozarelas spherification is hard to get a nice spherical form, do they drop it from spoons or use some other metod?
