I'd not made a cocktail with cream and egg white before, but I do love all things gin, so I thought I'd give this a try...and I'm so glad I did. It emulsified perfectly first try (I was not expecting it to go perfectly the first time lol), and it was just lovely. The foam has this lovely lemon-y scent, the drink itself is creamy and delicious. It tastes like a subtle combination of a lemon meringue and a key lime pie.

Mine had a couple of minor variations: I didn't have half n half, so I used half as much heavy cream (I had to eyeball it). And I accidentally overpoured the vanilla extract; I think it was maybe 1/4 tsp, but I'm not upset. I think it lends the drink a nice sweetness, and I think it's why it tastes so much like a summer dessert to me.
