Anyone who works in the restaurant business or is a fan of desserts on the plate knows this: a perfect quenelle is the signature of a great dessert. That elegant, smooth, three-sided shape turns a simple scoop of ice cream into a work of art. But making a perfect quenelle is not just a matter of dexterity and wrist. It is first and foremost a matter of the physics and thermodynamics of ice cream. Today we find out what the OQP is: the Optimal Quenelle Point.

If the ice cream is too cold, the spoon slips, the mass crumbles or forms unsightly cracks. If it is too hot, the spoon sinks well but the quenelle “sits” on the plate, losing its angular shape and melting in seconds. The perfect consistency should be reminiscent of that of soft mascarpone: the spoon should penetrate effortlessly, but the texture should have enough stickiness and tightness to keep the shape from collapsing.

For years, ice cream makers and chefs have gone by trial and error, pulling ice cream out of the freezer and waiting for “the right time.” Today, thanks to the advanced use of the Freezing Curve, we can calculate this state with pinpoint accuracy. We call it the Optimal Quenelle Point (OQP).

The Science Behind the OQP

Everything revolves around the percentage of frozen water within the mixture. The Freezing Curve shows us exactly how much water turns to ice at each individual degree of temperature.

Scientific literature teaches us that classic storefront ice cream (so-called hard ice cream) reaches its ideal consistency for serving on a cone or cup when about 75 percent of the total water is frozen. At this stage, the texture is firm and hard. Too hard, however, for a smooth, silky quenelle.

To reach the Optimal Quenelle Point (OQP), we need to move slightly higher on the freezing curve, increasing the liquid fraction (the unfrozen syrup) at the expense of ice. From empirical tests and thermal calculations, the OQP lies in a window between 65% and 70% frozen water.

Two physical magics occur at this level of freezing:

  1. Lubricating Effect: Having melted 5-7% more ice than at showcase temperature, there is a greater amount of liquid, viscous syrup enveloping the ice crystals and fat globules. This syrup gives the ice cream a great deal of “plasticity,” making it scoopable and slightly sticky, perfect for slipping into the hot spoon and curling in on itself.
  2. Structural Tightness (Stand-up): Since it is still 65 percent solid ice, the internal structure has not collapsed in the slightest. The quenelle will maintain its sharp, perfect angles even when in contact with a room-temperature dish or warm sauce, giving you the time you need for serving in the dining room.

How to find your OQP without going by trial and error

Each recipe has a different Freezing Curve based on the sugars and solids used. This means that OQP (65-70% ice) will be at a different temperature for a lemon sorbet than for a chocolate ice cream or a gourmet Parmesan ice cream!

On average, the OQP is about 1.5 to 2.5 °C warmer than the showcase serving temperature. But why guess?

By entering your recipe into advanced balancing software (such as BilanciaLi Gold), the program itself interrogates the Freezing Curve for you. The software will return two crucial temperatures to you:

  • Showcase Temperature (Classic Scoopability): e.g. -14.5 °C (at 75% ice)
  • OQP (Quenelle/Plating) temperature: e.g. -11.7 °C (at 70% ice)

Knowing this, you will simply set your service pit, or pass counter in the kitchen, to exactly the calculated OQP temperature.

🚨 SPOILER ALERT: Something new is coming!

This amazing feature of automatic calculation of OQP by freezing curve is currently under development for BilanciaLi Gold. I am personally testing and stressing it these days, and I assure you it will eliminate any blind attempts! It will be made available to all users within the spring.

And on that note, I have a surprise for you: only for today and tomorrow (March 15-16, 2026), to celebrate Quenelle Day, you have an exclusive chance to secure BilanciaLi Gold in “For Life” version!

By purchasing the license now with a one-time payment, you will be entitled to download all future updates forever (including the brand new OQP and Freezing Curve feature coming soon) without ever having to repurchase or renew the software next year.

Don’t miss this opportunity to take your plate desserts to a truly professional level, with math working for you behind the scenes.

Happy Quenelle Day and good balances! 🥄✨
