Reddit reviews The Joy of Mixology, Revised and Updated Edition: The Consummate Guide to the Bartender's Craft

Looks delicious!

Do try it with orange blossom/flower water if you can find it; it gives it a little more floral/perfumy quality than the orange zest. It’s super cheap if you buy it at a Mediterranean or Middle Eastern grocery store. I bought a bottle of it for less than $2.50 after tax.

You can get the same brand as the nice woman helping me recommended on Amazon, but it’s about twice as much.

Also if I may, try shaking it longer next time, despite your fingers. All the RGFs I've had (and made) have a thicker and finer foam; kind of like a light cream/meringue (soft peaks ideally). gaz regan actually recommends just throwing it in a blender. He says there's no texture difference, I claim I need to do more uh... research.

Now you have me jealous that it's too late to make one myself. :D
