Learned something today - went to the fridge for some salad dressing I made up a week ago- olive oil, vinegar, spices. It had solidified over a week. WTF?
Did some reading and apparently olive oil is rich in mono-unsaturated fat, which can solidify at lower temps. Poly-unsaturated fat, like corn oil and other vegetable oils, less likely to do so.
So, if you're making and consuming fresh dressing, olive oil is fine, but for storage other oils are probably better.
Also learned that if you let the dressing come up to room temperature it re-liquifies for use. But it's a nuisance! So my next batch will be made with grapeseed oil.
