Floral elderflower folded into a peach-cream custard, with St-Germain pulling everything toward a champagne-cocktail reading — late spring on a spoon.
This St-Germain elderflower peach ice cream turns a Hugo cocktail into a frozen custard with real peach purée and a small amount of cream cheese to bind the extra moisture from the fruit. St-Germain at 20% ABV is poured small to preserve the freeze structure while still reading clearly in the finish. The elderflower goes in off heat, after the custard is strained, because heat destroys the aromatics that make the spirit work. Peach purée beats extract every time — the extract reads candy-sweet, the purée reads orchard. Three machine methods, gram-precise, are built for people who take their late-spring cocktails seriously.

Why St-Germain Works in Ice Cream
St-Germain at 20% ABV cross-cuts cleanly with a custard base — same proof window that makes Frangelico work, so the ice cream sets firmly. The peach purée adds water and natural sugars; you compensate by reducing the dairy slightly and adding a small amount of cream cheese to bind the extra moisture. Elderflower’s volatile aromatics hit harder cold than warm — go in off heat after the custard is strained, not steeped. Real peach purée beats peach extract every time; the extract reads candy-sweet, the purée reads orchard.
What You’ll Taste
Peach hits first — ripe, juicy, slightly tart. Then the elderflower lifts: floral, lightly honeyed, almost lychee-adjacent. St-Germain ties it together in the finish, dry and aromatic, with the champagne-cocktail character that makes the original drink work. Long finish, just barely sweet, more aromatic than dessert-like.
Three Methods, One Recipe
 1 pint – 2-3 servings |  8-10 servings |  12 servings |
Technique Notes
Peach purée: blend ripe yellow peaches (skin on for color; off for a smoother purée) and strain through a fine-mesh sieve. 175 g purée per Standard recipe. Frozen peaches work in winter — thaw and drain excess liquid before puréeing. St-Germain goes in off heat after straining; heat destroys the elderflower aromatics. Don’t reduce the peach purée — concentrating it loses the fresh-fruit character; just compensate for the moisture with the cream cheese binder. Target 170-175°F on the custard.
What to Drink With It
A chilled glass of champagne or prosecco with a splash of St-Germain — the original Hugo cocktail in spirit. For coffee: avoid darker roasts, the peach gets crowded. A light Ethiopian or a mint tea works. Plate with shortbread or a thin almond cookie for texture.
Substitutions
St-Germain: there’s no real alternative — Pamplemousse Rose (grapefruit liqueur) shifts the profile entirely; floral elderflower is the whole point. If you can’t get St-Germain, make a different recipe. Peaches: nectarines read and taste very similarly; apricots shift toward being more tart. Avoid using peach schnapps — it’s almost all sugar, no real fruit. Cream cheese: do not skip; the moisture binding matters here more than in straight custard recipes.
Storage
Keeps 10 days in a sealed container with plastic wrap pressed to the surface. Fruit-forward bases lose brightness faster than dairy-only — the floral notes fade after the first week. Serve fresh when possible. Alcohol keeps the base scoopable. Do not refreeze after a full melt.
