You've heard, perhaps, of raw eggs in cocktails (Ramos gin fizz, eggnog), but in soda?! Yes, and it's better than it sounds.
Soda sữa hột gà, or Vietnamese egg soda, may seem odd, but it's surprisingly refreshing. Made from egg yolk, sweetened condensed milk, and club soda, it tastes like a rich, custardy ice cream soda.
If you're concerned about raw eggs and salmonella contamination, then this won't be the drink for you, but here's a recipe if you want to give it a try. I prefer to use pasture-raised eggs from a farm I trust.
Have you tried Vietnamese egg soda? What did you think?
Vietnamese Egg Soda (Soda Sữa Hột Gà)
Makes 1 drink2 tablespoons sweetened condensed milk, or to taste
1 egg yolk
1 cup club soda
Ice
Place sweetened condensed milk and egg yolk in the bottom of a glass. Fill glass with club soda and stir vigorously until combined.
Pour over ice and serve. Note: The carbonation may curdle the eggs slightly. If you like, you can strain it to remove any solid bits.

You can buy pasteurized whole eggs to use for raw recipes like this. I've used these to make eggnog for the past few years: http://www.safeeggs.com/
They're a little more expensive than your average egg, but getting them just occasionally for a special recipe isn't a big deal. And I like being secure in the knowledge that I'm not giving the whole family food poisoning on Christmas Eve.
You can also pasteurize whole eggs yourself, but it's a pain in the butt. Most of mine came out slightly cooked, and it's harder to crack the shells once they've been softened, so I ended up breaking a lot of the yolks on shell shards as I tried to separate them.
It's creamy and delicious! Sort of a sweet, effervescent light custard.
