Refrigerating olive oil

I made some mojo de ajo using Rick Bayless’s recipe. He says that it will keep for up to 3 months in the refrigerator, so I stored it in the refrigerator. The oil seems to have solidified in the refrigerator. If I leave it out for a bit, it melts again, but I am worried that refrigerating olive oil will harm its flavor. Is it bad to refrigerate olive oil to the point that it solidifies? Is it normal for olive oil to do this?

Best Answer

In my experience, that is completely normal and will not harm its flavor at all. You just need to warm it up before serving so that you can re-mix / emulsify your sauce / dressing. It congeals in the fridge much like any other fat will (think butter or bacon grease). Apparently, extra virgin olive oil may suffer from condensation in the bottle affecting the flavor. It may also turn cloudy.

But in general, you should be fine. Even if it does go bad, it should just affect the flavor and not be harmful, just gross. So if it tastes bad, toss it. Otherwise you're fine. Note: I'm just talking about the oil going rancid, not anything else you might mix with it.

Quick Answer about "Refrigerating olive oil"

Olive oil should not be stored next to the stove as this exposes the oil to consistent heat. It is also not recommended to store oil in the refrigerator because condensation within the bottle may lead to off flavors. Store your oil in a cool, dark cabinet or pantry.

Should olive oil be refrigerated once opened?

Even after being opened, refrigeration is not necessary as long as stored properly. However, if you won't be using an opened bottle for several weeks, refrigeration may help preserve the oil until you need it. Just be sure to let it warm to room temperature afterward so that it is completely liquid before using.

Does it hurt to refrigerate olive oil?

Refrigeration will extend the life of olive oil without harming the oil. The oil will become cloudy and solidify in the refrigerator, but this will not significantly affect the quality or flavor. When the oil is warmed to room temperature it will return to a liquid state and its color will be restored.
