Some ingredients go unnoticed, yet without them, nothing would taste quite the same. Vinegar is one of them. Discreet and essential, it’s the invisible foundation that brings balance, depth and character to countless recipes. In our kitchens, it’s almost always present — in salads, marinades, pickles, escabeches… and of course, in sauces. And its presence is no accident.
Common everyday sauces like ketchup, mayonnaise or salsa brava all share one thing in common: vinegar. This ingredient not only provides that characteristic tang, but also helps preserve, balance and deepen flavour, and contributes to a smoother texture.
Vinegar acts as a natural flavour enhancer, supports emulsification and improves food preservation, especially in homemade recipes. In fact, the most widely consumed sauces in Spain traditionally contain vinegar:
- Salsa brava: often includes vinegar to intensify the heat and add acidity.
- Ketchup: vinegar is essential to balance the sweetness of tomato and sugar.
- Mayonnaise: the acid helps emulsify the egg and oil and stabilises the mixture.
- Mustard: many versions include vinegar to enhance flavour and improve texture.
Other sauces, such as romesco (traditionally served with calçots in Catalonia), mojo picón from the Canary Islands, or cocktail sauce (widely used with seafood), also rely on vinegar.
Sauces of the World
This ability to bring coherence and harmony is universal. Wherever there’s a cuisine with identity, there’s vinegar. In China, it’s at the heart of sweet and sour sauce; in Japan, it elevates the flavour of ponzu; in Argentina, it energises chimichurri; and in the Philippines, vinegar is not just added — it’s the base of iconic dishes like adobo, both preserving and flavouring.In Eastern Europe, vinegar appears in tangy or spicy sauces that accompany smoked meats, as well as in traditional pickles and mustards. In France, vinaigrettes are a whole universe of their own, often made with wine, cider or champagne vinegar. In the UK, vinegar is a non-negotiable for fish & chips. And in India, it’s essential in spicy marinades and curries like vindaloo, reflecting the legacy of Portuguese cuisine.

Why do these sauces contain vinegar?
Vinegar plays several essential roles in sauces — each equally important:
It balances flavours
Its natural acidity cuts through fats, brings freshness and softens sweetness or intensity from ingredients like mustard, tomato or eggs. This ability to round out flavours is key for well-balanced sauces.
It preserves
Vinegar is a natural preservative. Long before refrigerators, our grandparents used vinegar for pickling and to extend shelf life. Even today, its role in preserving food — especially in artisanal or homemade sauces — remains vital.
It affects texture and colour
In some sauces, such as sweet-and-sour blends or emulsified types, the kind of vinegar used can subtly influence both texture and appearance. Choosing the right vinegar is as much a technical decision as it is a creative one.
Play, combine and create
Vinegar isn’t just an ingredient — it’s a gastronomic tool. It allows you to modulate intensity, add contrast or softness, and create dynamic flavour profiles between sweetness, saltiness and bitterness. The type of vinegar you choose can completely change the outcome of a dish.
For example, aged balsamic brings depth and woody notes, apple vinegar offers lightness and freshness, cava vinegar adds elegance and subtlety, and sweet-and-sour vinegars open up a world of surprising and layered flavours.
