Opened mayonnaise: one-month limit, while jarred alioli is a guessing game

Peine mayonnaise: a one-month limit, alioli remains a guessing game

Buying a jar of alioli for a single person is a gamble. You open the sauce, use it twice, and it sits in the fridge door while you wonder whether it will keep or whether it is time to throw it out. The doubt is no small matter: most jars carry not a single indication of the maximum storage time once peine. Only the generic advice to keep it refrigerated.

The most concrete answer to this question has come from a store brand. **DIA** mayonnaise jars sold upside down state on their label a **maximum of one month** after opening, according to a participant in the thread. It is the only explicit figure found after checking brand after brand. From there, the obvious conclusion is by analogy: if the composition of alioli is similar to that of mayonnaise, the same timeframe should apply to an peine jar of alioli. No one has yet found a label that confirms this in writing.

Can you freeze jarred alioli?

The temptation to freeze it in ice cube trays, as people do with tomato sauce, runs into a technical problem. Alioli and mayonnaise are **emulsions**, and emulsions break easily when frozen: the result is a split sauce, with the oil separating from the water phase, as a forum user warns. The home experiment is possible, but the outlook is not good. Anyone who has tried it and got an acceptable result has not written it down.

It is worth separating two things. One is industrially packaged sauce, stable thanks to its preservatives and pH, and quite another is homemade mayonnaise, which contains raw egg and is a breeding ground for bacteria. The antiestéticar of egg, which is widespread, applies even more to the homemade product than to the store-bought jar. In the industrial product, the egg is pasteurised or in derivative form, and the manufacturer adjusts the acidity to curb microbial growth.

Egg-free alternatives and small containers

For those cooking for one, the format matters as much as the recipe. There are egg-free aliolis in small containers that keep well and, according to one participant's experience, taste better than the best-known garlic mayonnaise brands. It is a middle path: you spend less, throw away less and avoid the freezing dilemma.

The underlying calculation is simple. A large jar is better value per kilo, but if half of it ends up in the bin, the saving evaporates. Individual sachets, which is what people usually resort to when there is no other option nearby, make each portion more expensive and are not always available outside large cities.

The DIA one-month label is, for now, the only compass. Everything else is inference.
