I tried to use direct albumin (egg white powder). This works nic and this is powder - it is by default pasteurized. Only issue is that double strain is important and it may be a bit hard to transform powder to liquid state, so longer shake is preferable.
For me it was unbalanced. Yeah, there is less bitterness from campari in there, but everything else is more like separate in separation. Either agave syrup should be changed or something else is needed.
Nice refreshing, slightly acidic drink. If you want sour cocktail with bubbles and don't want too much of dry prosecco taste, this is good variant.
This is less exciting than it sounds. The combination of lemon juice and orange juice overpower the honey and the gin. Drink a screwdriver instead.
Honey mostly overpowers everything in the other cocktail - Merchant of Venice, and there only 2 spoons are used. Unless you did your syrup in wrong way, honey cannot overreach lemon and orange juice, counting, that their amount is smaller that in mentioned cocktail. Of course, bad honey (as well as bad alcohol) can destroy everything, but you should know what you are making cocktail of beforehand, obviously.
Nice longdrink. It makes Jagermeister specific taste more smooth and pretty sweet.
