The Sauce Census

The 3:1 rule is not what chefs do

Culinary school teaches a 3:1 ratio of fat to acid for a basic vinaigrette. We measured fat and acid volumes across 719 vinaigrette recipes in the catalog, 660 of which declare both quantities cleanly enough to compute a ratio.

The median chef recipe runs sharper than the textbook, at 2.4 parts fat to one part acid rather than 3 to 1. Only 17% of measured vinaigrettes land within 10 percent of the rule, between 2.7:1 and 3.3:1. The rest spread wide in both directions, from under 1.5:1 to well over 4:1.

Lemon beats every vinegar

Across every category in the catalog, lemon juice appears in 609 recipes, more than any vinegar. Red wine vinegar is the top vinegar at 251 recipes.

Dijon is the quiet workhorse

Dijon mustard shows up in 454 recipes, 17% of the whole catalog. Inside vinaigrettes specifically it climbs to 29% of recipes, doing double duty as flavor and emulsifier. It is not alone there: 37% of vinaigrettes carry some emulsifying ingredient, whether that is mustard, egg yolk, or another binder.

What 835 chefs reach for

Salt and olive oil lead by a wide margin. After that, the list settles into the pantry staples that show up across almost every chef in the catalog, regardless of cuisine or category.

Three stars, same pantry

101 chefs in the catalog have held three Michelin stars, contributing 414 sauces. Their recipes average 6.6 ingredients per sauce, against 6.9 for the field. Elite kitchens do not reach for more ingredients. If anything, they use slightly fewer. See the full list on the three-star kitchens page.

The catalog

Vinaigrettes and dressings make up the largest share of the catalog by category, followed by mayo, pan sauces, and herb sauces.
