Mixing a high-PUFA olive oil (Arbequina) with a more stable one (Picual) makes the blend more heat-resistant—less gunk forms when you fry with it.

Mixing olive oil with more Picual (which has more monounsaturated fat) makes it less likely to form gummy polymers when heated, compared to mixing with more Arbequina.

When olive oil gets super hot (200°C), it starts forming gummy, sticky molecules called dimers—some oils make way more than others, especially blends high in Arbequina, while Picual makes the least.

Some olive oils — like Picual and Cornicabra — hold up better when heated than others, like Arbequina and Manzanilla, because they lose fewer healthy compounds and form less gunk when cooked.

When olive oil gets super hot, it starts forming gummy, big molecules called dimers — and the amount depends on the type of olive oil: blends with more Arbequina make way more than those with more Picual.

Some olive oils, like Picual and Cornicabra, handle high heat better than others—they keep more of their good stuff and make less gunk when cooked.
