Sugar and alcohol lower the freezing temp for liquids. I don't recall the %'s off hand, but you can find them in McGee. You wont be able to get the strong alcohol taste (you can get the other flavors of the liqour though) and fluffy texture at the same time.
On a side note, at a place I staged at, they did an amuse bouche that had a garnish of frozen plantain/banana shredded with a microplane just prior to service. |
