Spain’s supermarket sauces: fried tomato beats Mercadona

Supermarket sauce guide: which are worth buying and which are just syrup

With the shopping basket acting as a social thermometer for the past five years, a discussion spanning more than four years has finally established which large-chain sauces deserve a spot on your shelf. The initial question was simple: what can you buy at Mercadona, Lidl, Aldi or Carrefour without settling for an ultra-processed product? As usual, there is no single answer. It started with a discount store’s fried tomato sauce, considered acceptable by its author, “not as coarse” as the standard options.

From the first message to the last, the repertoire jumped from piri-piri to Laoganma. That is, from the humblest sauce on the aisle to Chinese chili oil paste. 1,585 days allow for plenty.

Tomato sauce: where consensus breaks down

Fried tomato is the battleground. Against those defending traditional industrial brands, an uncomfortable stance emerges: it is argued that fried tomato acts as a laziness detector, because a sofrito of garlic, onion and crushed tomato takes three minutes to make, and with good oil, the stew turns red, not orange. The criticism isn’t about taste; it’s about substance.

On the other side, two specific brands receive praise. One “plays in another league” compared to private-label options suitable for daily use, and the pesto rosso from a German chain, cited as the best ally to finish off a ready-made tomato sauce. Regarding pink and ranchera-style sauces, the recommendation is to turn to a classic cannery’s version, cheaper than imported competitors.

From piri-piri to sriracha: how heat rises

The next step up is spicy. A jarred piri-piri sauce is described as excellent for spreading and adding life to bland white meats. The silent revolution arrives with sriracha, a Thai-origin condiment sold in a consistent package—clear body and green cap, with a spicier red-cap version—that has carved out space on shelves. The most repeated verdict: it is too salty and improves when mixed with mayonnaise.

One rung higher is chipotle tabasco, appreciated for its smoky flavor, and a Mexican habanero sauce sitting around 100,000 Scoville units. According to tasters, it packs more punch than others with much higher theoretical scores. Harissa also makes the favorites list for a pork loin sandwich with peppers.

The classics nobody disputes

There is a block that admits no nuance. Lea & Perrins Worcestershire sauce comes with a stark warning: no imitations accepted. Its profile, based on vegetable extracts and fermented anchovies, places it—according to a widely celebrated opinion—in the podium of British contributions to world gastronomy, alongside Stilton cheese. The star use is steak tartare, and a few drops in bolognese elevate the dish via umami.

The same happens with classic Tabasco: the original version beats trendy flavors. Mustard enters this small group of processed sauces that are saved, along with spicy ones, because they are used in minimal doses.

The international assault: Laoganma, adjika and sesame

The most exotic stretch belongs to imported sauces. Chinese Laoganma, a chili oil and fermented soybean paste, is recommended for noodles. Caucasian adjika, based on pepper, garlic, tomato and spices, is found in Slavic product stores. Japanese sesame sauce is described as pure drug for salads, and hoisin—the one for Peking duck—is enough to build a whole dish with frozen bao buns and bacon.

For fish and chicken, teriyaki sneaks into the favorites. The shared homemade trick: soy sauce, a splash of whatever alcohol is at hand, and star anise produce an almost identical result. The breakdown of that recipe, with quantities, is one of the most consulted details.

How much sugar is in a supermarket sauce?

Here comes the fine print, and it’s significant. One declared sauce contains 8.8 grams of sugar per 100g, and another, 2.3g. The difference matters because these sauces aren’t used drop by drop, but spoonful by spoonful, and the calculation involves multiplying those values by what you put on your plate.

There are products where the proportion is alarming. Chimichurri from a well-known supermarket chain is described as 90% glucose syrup with some herbs and seasonings, and sweet-and-sour doesn’t fare better. Against that, the usual argument: spicy sauces are dosed in minimal amounts, so their nutritional impact is residual.

---

The inventory remains open at a point nobody closes. On one hand, the convenience of the jar and the consistency of industrial flavor; on the other, the suspicion that almost everything can be made at home with better ingredients and less sugar. The conversation has lasted more than four years and still lacks an arbiter.
