Apple-Peas Highball

The Apple-Peas Highball is Jean-Félix Desfossés' answer to a question most people never ask: what does a sugar snap pea taste like once you take the vegetable out of it? Juiced with Granny Smith apples, clarified with a pectic enzyme until it runs clear, corrected with citric and malic acid, and then carbonated hard — it comes out bright, faintly grassy, and startlingly clean. This is a modernist drink and I am not going to pretend otherwise. It needs a juicer, an enzyme, a scale, and a way to force CO2 into liquid. What it does not need is any excuse for the flavour.

Why Clarify At All

Desfossés is a Québécois bartender who spent a decade running the mixology programme at a five-star hotel before becoming better known as Truffles On The Rocks. He published this one in a booklet built around clear ice, and the drink is very obviously the work of somebody who thinks about clarity for a living. Raw apple and pea juice is opaque, grey-green, and full of suspended pulp. Pulp is the enemy of carbonation: every particle is a nucleation site, so a cloudy liquid throws its bubbles off the instant you pour it and goes flat while you are still looking at it.

Clarifying with Pectinex — a pectic enzyme, dosed here at a quarter of one percent of the juice weight — breaks down the pectin holding that haze in suspension so the solids drop out and can be strained off. What is left keeps the aroma and loses the texture. The carbonation then holds, and the drink reads as clean rather than as vegetable juice with gin in it. The ascorbic acid added at the juicer is doing separate work: apples brown within minutes of being cut, and half a gram of vitamin C per batch stops that before it starts.

The Spec

This one is batched by design — the recipe below makes two drinks, because a cream whipper needs enough volume to carbonate properly and a single serve does not give it that. Five ounces of apple-peas cordial, an ounce and a half of a floral gin, half an ounce of Poire Williams, all of it charged with CO2 and poured over ice into two highball glasses. The spirit load per glass is about an ounce, which puts this well down in sessionable territory.

Floral gin, and what that rules out

A juniper-heavy London dry will fight this. The cordial's whole register is green and delicate — apple skin, raw pea pod, a little acid — and pine on top of it reads as interference. Reach for the gins built around floral and citrus botanicals instead: Hendrick's, Nolet's, Gin Mare, Monkey 47 at a push. If London dry is what you have, cut it to an ounce and let the cordial carry more of the glass.

Charge, vent, charge again

The double-charge is not superstition. The first CO2 charge displaces the air sitting in the headspace of the whipper; venting expels that air-and-CO2 mixture; the second charge then dissolves into liquid that has nothing else competing for space. Shake ten to fifteen seconds on each charge, chill the whole thing for a few minutes before you release the pressure, and pour slowly down the side of a glass already full of ice. Cold liquid holds far more dissolved CO2 than warm liquid, which is why the chilling step is not optional.

If you have a carbonation rig

Use it. A dedicated carbonation setup — a CO2 tank, a regulator, a carbonation cap on a PET bottle — gets finer bubbles and holds them far longer than a cream whipper does, because you can run it at a steady pressure over minutes rather than in two violent bursts. The whipper is the version that works with equipment people already own. It is not the better version.

Bottom Line

Everything about the prep list says this should taste like a science project, and it tastes like a garden in April. That is the whole trick of clarification, and this is one of the clearest demonstrations of it I have made at home. Snap pea is not a flavour anyone is short of in a cocktail — right up until you have this, and then it is. Garnish it with a raw pea and do not apologise for that.
