There is a new craze in Japan, the company Ikezo has released sparkling sake in a can that is a fluid liquid. The sake is a mixture of liquid and a gel. Visually it looks like the sake has jelled but the carbonation bubbles rise up through the liquid . To prepare the can must be shaken before opening, I believe this is because the gel is set and shaking it allows the gel to partially return to its liquid form.
You can see a video of the Ikezo Sparkling Jelly Sake here:
I'd love to think of the right way to reproduce this. I assume the right way to do it is set a gel in an iSi siphon, shake, then release the gas before pouring into a champagne glass. But the question is, which gel would be best suited for this purpose and at what ratios? Gelan? Agar? Gelatin? Any other ideas?
