Sauce Choron
Sauce Choron is a beautifully simple variation of Béarnaise. Named after Alexandre Étienne Choron, it proves that even the most perfect sauces can be improved with a single ingredient: a teaspoon of concentrated tomato paste, cooked to a deep rust color.
The genius of Choron lies in umami layering. Tomato paste is one of the richest natural sources of glutamates, and when these are dissolved into the high-fat matrix of a Béarnaise, they create a lingering savory depth that the original sauce lacks. The visual transformation is equally striking — the pale gold of the Béarnaise shifts to a warm sunset orange, signaling a richer, more complex flavor profile. It's a one-minute upgrade that turns a leftover Béarnaise into what feels like an entirely new sauce.
History & Origins
Alexandre Étienne Choron was the chef of the Voisin restaurant during the Siege of Paris (1870). When food ran out, he famously cooked the zoo animals (elephants, antelopes). While the animals were a necessity, the sauce was a masterpiece of luxury.
The Science
Umami layering. Tomato paste is rich in glutamates. When combined with the high fat content of the Béarnaise, it creates a lingering, savory mouthfeel that the standard sauce lacks.
Technique
The 'Pincé'. Don't just add raw tomato paste. Sauté the paste in a tiny bit of butter until it turns a deep rust color. This removes the metallic, raw acidity and unlocks its natural sugars.
Common Mistakes
Adding too much tomato. The sauce should be a pale pink/orange, not red. If you add too much, the tomato flavor will overwhelm the delicate tarragon of the Béarnaise base.
Chef's Notes
Choron is the secret 1-minute upgrade for leftover Béarnaise. It breathes new life into the sauce and makes it feel like an entirely different course for the next day's meal.
