Can I use Cointreau instead of Grand Marnier?

You can, and you'll have a very good drink, but it won't be a Cadillac. Cointreau is clean, dry, and orange-forward with no spirit base of its own. Grand Marnier is cognac with orange, so it brings weight and a touch of barrel warmth that the whole Cadillac premise depends on. Use Cointreau and you've made a top-shelf standard Margarita. That's not a downgrade, just a different drink.

Is the float actually worth the effort?

Yes, and it costs you nothing but a slow pour over the back of a spoon. The quarter ounce sits on top and hits your nose before the first sip, then folds into the drink as you go. Stir it in at the start and you've wasted it. The whole point is the layered delivery.

Why agave nectar instead of simple syrup?

Agave comes from the same plant family as the tequila, so it sweetens in the same register instead of dropping a clean sugar note that sits apart from everything else. It also has more body, which gives the finished drink a slightly rounder texture. Dilute it roughly one to one with warm water first so it pours and mixes properly, because straight agave is thick and stubborn in a cold shaker.

The Cadillac Margarita: A Daisy in a Better Suit

Every bar has a Cadillac Margarita on the menu, and most of them are a lie. The name promises luxury and the execution delivers sour mix with a splash of orange liqueur somebody comped from a sales rep. Done right, though, this is a serious drink. Reposado tequila with a little time in oak, real Grand Marnier doing actual structural work, fresh lime, and a float that announces itself before the glass reaches your mouth. It is the Margarita that grew up and bought a nicer jacket.

2 ozReposado Tequila

0.75 ozGrand Marnier

1 ozLime Juice

0.5 ozAgave Nectar

Garnish: Lime wheel

Shake it, hard, over plenty of ice. You want the dilution and the cold, and you want the lime juice and agave to emulsify into something with a little body. Fresh lime only. Agave nectar instead of simple syrup is the right call here because it echoes the tequila instead of fighting it, and it carries sweetness without the cloying weight of sugar syrup. Strain over fresh cubed ice in a rocks glass, not the bruised shards from the shaker. The salt rim is a choice, not a rule, so do half the glass and let the drinker decide. The quarter ounce of Grand Marnier floated on top is the whole trick of the name. It sits there as a hit of warm orange and oak that the cold drink underneath delivers in a second wave. Skip the float and you have just made a good Margarita. Add it and you have made the Cadillac.

Strip away the tequila and the salt and you are looking at a Sidecar. The Sidecar family is built on a simple, ruthless logic: a complete sour, meaning spirit plus citrus plus sweetener in balance, where the sweetener's job is partly handed to a structural liqueur. In the classic Sidecar that liqueur is orange. Here it is Grand Marnier, the cognac-based orange liqueur, poured at three quarters of an ounce, comfortably under the two ounces of base spirit. That ratio is what keeps it a daisy and not a liqueur cocktail. The Grand Marnier sweetens, adds aromatic depth, and binds the lime to the tequila, but it never leads. Swap the base and the proportions and you can walk this same blueprint to a Cable Car, a Between the Sheets, a Champs-Élysées, or a Brandy Crusta. They are all the same machine wearing different shirts. Understanding that is worth more than memorizing fifty recipes, because once you see the skeleton you can fix any of them when it tastes wrong.

The Margarita itself is a Tequila Daisy, and daisy is just Spanish-adjacent shorthand that ran through a dozen origin myths nobody can prove. The Cadillac version is an American steakhouse invention, born in the era when upselling was an art form and the word premium meant something on a wine list. The idea was sound even if the marketing was greasy. Take the workhorse Margarita and reach for the good orange liqueur. Grand Marnier brings cognac underneath the orange, which gives the whole drink a backbone the cheap stuff cannot. The reposado matters too. Blanco tequila is bright and vegetal and perfect in a standard Margarita, but reposado's few months in barrel give you vanilla and a softer edge that meets the Grand Marnier halfway. The float is theater, sure, but it is honest theater. It does real work on the nose. Most bars ruin this drink by treating Cadillac as a price point instead of a recipe, charging fourteen dollars for the same sour mix in a salted glass. Make it at home with real ingredients and you will understand what the name was supposed to mean before the chains got hold of it.
