What makes it a Cadillac margarita?
A Cadillac margarita is basically the “upgrade” version: it uses a higher-end orange liqueur, most commonly Grand Marnier (or sometimes Cointreau or curaçao). Some bars mix it in, some float it on top, and some do both. The vibe is smoother, a little richer, and a little more special-occasion than a standard triple sec margarita.
Should I use reposado or blanco tequila?
I like reposado here because it can bring a rounder, softer finish that plays well with orange liqueur. If you want a sharper, brighter margarita, use blanco. Both are correct, your mood decides.
Do I have to float the Grand Marnier?
Nope. You can shake it in. Floating gives you that orange aroma on the first sip, which is the whole Cadillac flex. Shaking it in makes the drink more evenly orange-forward.
How do I keep it from being too sweet?
Start with 1/4 ounce agave and adjust after your first sip. Also, make sure your lime juice is fresh. Bottled juice can taste flatter and sometimes reads sweeter, even when you do not add extra sugar.
Can I make it without a cocktail shaker?
Yes. Use a jar with a tight lid, shake hard, then strain. Or stir vigorously with lots of ice for 30 seconds, but shaking gives the best chill and texture.
What salt is best for the rim?
Kosher salt is my go-to because the flakes taste clean and not aggressively salty. Fine table salt can make the rim feel harsh.
What can I use instead of Grand Marnier?
Cointreau is the cleanest swap. Orange curaçao also works and leans a little more orange-candy in a fun way. If you only have triple sec, it will still be tasty, just less “Cadillac.”
