Aioli originated on the Mediterranean coast of France and Spain as a simple garlic‑oil emulsion. In Provence, it is traditionally served with boiled vegetables, fish, and as a dip for crusty bread, reflecting the region’s love of bold, garlicky flavors.

In Provence, classic aioli is just garlic, olive oil, and salt, sometimes thickened with egg yolk. In the south‑west, a small amount of mustard or lemon juice is added for brightness. Some coastal versions incorporate saffron or herbs like thyme.

It is typically presented in a shallow bowl alongside boiled potatoes, steamed green beans, and grilled fish. Diners spoon the aioli over the vegetables or dip each bite directly, creating a communal, rustic dining experience.

Aioli is a staple at summer barbecues, family picnics, and Provençal festivals such as the Fête de la Saint‑Jean, where fresh seafood and grilled meats are paired with the garlicky sauce.

Its simplicity—just garlic, oil, and an emulsifier—highlights the quality of the ingredients. The technique of slowly emulsifying oil into a yolk creates a luxurious, glossy texture that is both a condiment and a showcase of culinary skill.

Adding oil too quickly, using a warm yolk, or not whisking continuously will cause the emulsion to break. Also, using low‑quality oil can result in a bitter flavor.

A 1:20 ratio yields a lighter, more pourable aioli that is easier for beginners to emulsify while still delivering a rich mouthfeel. The extra acid and mustard help stabilize the larger oil volume.

Yes, store the finished aioli in an airtight jar in the refrigerator for up to 7 days. Keep it chilled and bring it to room temperature before serving for optimal texture.

The aioli should be thick yet pourable, with a glossy sheen and a smooth, velvety mouthfeel. When lifted with a spatula, it should hold its shape without dripping.

Since aioli is not cooked, "done" means the oil has fully emulsified into a stable, glossy sauce. If the mixture looks separated or watery, continue blending and add a few drops of warm water.

The YouTube channel Fallow focuses on foundational cooking techniques, ratio‑based recipes, and practical kitchen science, helping home cooks understand the why behind each step.

Fallow emphasizes precise ratios and the chemistry of emulsions, breaking down classic sauces like aioli and béchamel into simple, repeatable formulas, whereas many channels rely on vague measurements.
