Here’s your cheat sheet: use seltzer when you want pure, unadulterated bubbles—mixing with juice, hydrating without calories, or pretending you’re on a health kick while still drinking fizz. Use club soda when you’re making cocktails, especially things like a Tom Collins, a Mojito, or a highball where you want the liquid to do some heavy lifting.
Dare I say it? Club soda also works better in baking. That extra salt can help yeast rise and give your pancakes a fluffier texture. Yes, I’ve made club soda pancakes. No, I’m not ashamed. Just a little carbonated and proud.
