Fluffy Duck
The Fluffy Duck is the advocaat bottle’s night out: Dutch custard liqueur lifted with gin and orange, lengthened with soda into a 1970s party classic whose name describes the texture and whose texture keeps the promise. The build balances custard against botanicals. Advocaat and gin at matched measure, with the gin performing on custard exactly the trick juniper performs on cream in an Alexander, cutting the richness so the drink stays a drink. Orange juice brightens it, triple sec doubles the orange from the liqueur side, and the soda lofts the whole thing into the fluff the duck is named for. It drinks like a float that learned manners: sweet, soft and considerably more refreshing than a custard-based cocktail has any business being. Advocaat gets two outings a year in most households, and this is comfortably the better of them and the one that has nothing at all to do with Christmas.
Glassware: Highball Glass
Garnish: Orange Slice and Maraschino Cherry
Ingredients
30ml
The custard on its night out: thick, eggy and sweet, and it needs a hard shake to loosen properly before anything else can lift it.
30ml
The lift, at matched measure. Its botanicals cut the custard the way juniper cuts cream in an Alexander, which is what keeps this a cocktail rather than a dessert.
15ml
The fuller reading’s orange double, coming at the fruit from the liqueur side while the juice comes at it fresh. Fifteen millilitres is plenty given the sweetness already present.
30ml
The brightness, squeezed rather than poured. There is a great deal of sugar in this glass already, and carton juice adds more where acid is wanted.
60ml
The fluff itself, lofting the shaken custard to party height. Added last and stirred exactly once, because a proper stir knocks the air straight back out.
Instructions
Shake the advocaat, gin, triple sec and orange juice with ice for 10 seconds.
Strain into an ice-filled highball.
Top with soda water and stir once, gently.
Garnish with an orange slice and a cherry.
Expert Tip
The gentle final stir is what preserves the loft, and the loft is the whole drink. Once the soda goes in, one slow turn is enough to lift the shaken base through it; stir it properly and you knock the air out of both the advocaat and the carbonation, which leaves a flat, sweet glass with nothing fluffy about it. Shake the base hard first, though. Advocaat is thick and needs real force to loosen and aerate, and ten seconds of proper shaking is what gives the soda something to lift. Squeeze the orange juice too. There is a great deal of sweetness in this glass already, and carton juice adds more sugar exactly where the drink needs acid instead.
Flavour Profile
The Origin
The Fluffy Duck waddles out of the 1970s party-bar canon, authorless in the decade’s usual manner and popular across the advocaat-drinking nations.
The Dutch custard liqueur’s export market invented its cocktails communally rather than through any single bar, and this one’s name did most of the selling. Versions vary: some run on lemonade rather than soda, some add cream, and the Australian reading differs from the British one. What holds across all of them is advocaat lifted by something botanical and lengthened by something fizzy.
The Custard Lift
Advocaat needs two things done to it at once: cutting and lofting. On its own it is thick, sweet and closer to a dessert sauce than a drink.
Gin does the cutting. Its botanicals perform on custard the same job juniper performs on cream in a gin Alexander, giving the richness something dry and aromatic to work against so the glass does not simply read as sweet. The soda does the lofting, turning a thick base into something light enough to drink tall. Heavier cream-based readings of this drink exist and they lose the fluff, which is the part worth keeping.
The Orange Doubling
There are two oranges here and they arrive differently. The fresh juice brings acid, brightness and a little body; the triple sec brings concentrated peel sweetness from the liqueur side.
Between them they give the drink a width of orange character that either alone would miss, and more usefully the fresh juice supplies the only real acid in the glass. Everything else here is sweet. Fifteen millilitres of triple sec is enough, and pushing it higher tips a drink that is already sugary into something that stops refreshing halfway down.
The Advocaat Pair
The bottle gets two outings and this is one of them. A Snowball is advocaat with lemonade and lime, sharp and Christmas-shaped; the Fluffy Duck is advocaat with gin and orange, softer and built for a party.
Lemonade’s sharpness against orange’s sunshine, essentially, with the gin as the Duck’s extra structural argument. Serving both in December is the quickest way to show that advocaat has more range than its reputation suggests, and the Duck is reliably the one that surprises people more.
How to Serve It
Tall, over plenty of ice, cheerfully dressed with an orange slice and a cherry. It is a party drink from the decade that perfected them and it should not be served apologetically.
It also converts advocaat sceptics faster than any amount of explanation, largely because most people’s objection is to the texture of the liqueur neat rather than to its flavour, and the soda solves exactly that. One gentle stir at the end, and out it goes.
The Spirit
GinA flavour requirement rather than a method. The law asks only that juniper be the predominant taste and that the spirit reach 37.5%, which leaves everything else on the botanical bill to the distiller and permits a gin that was never redistilled at all.
Frequently Asked Questions
What is a Fluffy Duck?
A 1970s party classic built on advocaat: the Dutch custard liqueur with gin at matched measure, orange juice and triple sec, lengthened with soda water into the light texture the name promises. Served tall over ice.
Why gin with advocaat?
For the same reason gin works in an Alexander. The botanicals cut through the custard’s richness and give it something dry to work against, which keeps the glass a cocktail rather than letting it slide into being a dessert.
How does it relate to the Snowball?
They are the same bottle’s two outings. A Snowball is advocaat with lemonade and lime, sharp and Christmas-shaped; the Fluffy Duck is advocaat with gin and orange, softer and built for a party rather than a tree.
Why has mine gone flat?
Almost certainly the final stir. Once the soda is in, one slow turn is all it takes; a proper stir knocks the air out of both the shaken advocaat and the carbonation, and the loft that gives the drink its name goes with it.

Snowball
The Snowball is advocaat, sharp lemonade and a squeeze of lime, built tall over ice. It is a British Christmas fixture and it is a better drink than its reputation allows. Advocaat is a Dutch liqueur of egg yolk, sugar and brandy, thick and pale and closer to custard than to anything else on the back bar. On its own it is far too rich to drink. Lengthened with something sharp it turns into exactly what it should be, which is the entire trick of the Snowball. The lemonade is therefore the whole balance, and it has to be genuinely sharp. Advocaat brings all the sugar the glass can take, so a sweet lemonade produces something closer to a dessert than a drink. The lime is a modern addition and a good one, adding an acidity the original never had. It reached British sideboards after the war and the 1970s made it universal. Nostalgia keeps it there.
Harvey Wallbanger
The Harvey Wallbanger is a Screwdriver that took a swerve: vodka and orange juice with a float of Galliano, the tall golden Italian liqueur, and the most successful drinks-marketing campaign of the 1970s attached. The recipe is credited to Hollywood bartender Donato “Duke” Antone in the 1950s, but the fame belongs to Galliano’s importers, whose surfing cartoon mascot Harvey put the drink on every American bar and airline by 1975. The float is the whole idea: fifteen millilitres of Galliano’s vanilla-anise gold resting on the surface, so the drink opens herbal-sweet and finishes as a plain Screwdriver, the same descent-through-a-layer trick the New York Sour plays with wine. Stirred in, it is merely sweetened orange juice; floated, it is a drink with a beginning, middle and end. It collapsed with the decade and returned with the revival’s soft spot for honest kitsch: the modern reading pours fresh orange juice, keeps the float floating, and lets a very silly name introduce a rather clever structure.
Golden Cadillac
The Golden Cadillac is a Grasshopper with Galliano where the crème de menthe should be, and the swap turns a cold after-dinner mint into something closer to crème brûlée. Galliano's vanilla and soft anise sit against white crème de cacao and cream in equal thirds, and the drink comes out gold, thick and unapologetically a dessert. Its origin is unusually well documented for a drink of this kind. It was made in 1952 at Poor Red's, a barbecue roadhouse in El Dorado, California, for a couple who had just bought a gold Cadillac. The bar kept making them, and kept making them, and ended up one of the largest single accounts for Galliano anywhere in the world. That is the whole appeal. It is not a subtle drink and it was never trying to be. It is a small-town bar's celebration cocktail that outlived the celebration by seventy years and is still being shaken in the same room.
