Cooking oil shortage.

[rjb]

I read in the news about a shortage of cooking oil. I've heard stories about drivers adding it to their diesel cars but this takes the biscuit.

We’ve had a spate of used cooking oil thefts in the area. That’s where it’s gone then.

Cooking oil?
Wot's that?

We use olive oil.

Only posh people use olive oil and they eat spinach too.

Been frying with light-in-colour olive oil for years bought from Morrisons.

Last time we used "oil' it was sunflower oil.

There are many differences between "vegetable oil" and olive oil. One is cost: that's about three time the price of Morrisons' vegetable oil.

That's a lot more expensive for many people.

By the time you've figured out the various flavour profiles, smoke points and heat tolerences, and compared them with the temperature you tend to cook at, you might as well have bought a micro-wave!

It may be more expensive but surely the health benefits outweigh the cost. I mean how much vegetable oil do people even use these days or do folk till have deep fat fryers on the go? 500ml would probably last us a couple of months (and the rest ) and we probably use it in smaller quantities every other day.

This shortage was forecast a month or so ago so I stocked up with a couple of litres of olive oil back then.

It's just about impossible to calculate health benefits for individual dietary substitutions. The long-term experiments haven't been done and we have to resort to extrapolations and generalisations.

Powering Aeroplanes with used cooking oil seems like a waste of valuable resources to me, but then I’d like to see Av Gas heavily taxed in the way that ICE road vehicle fuel is. The article goes on to talk about the use of hydrogen fuel, that might be a more sustainable option and one that could be ramped up in volume.

Vegetable oil is usually rapeseed oil which is a fraction of the price of olive oil. Most people dont read the label and buy extra virgin rapeseed oil which is much more expensive.
Nice olive oil is great on your pizza, never use it for cooking.

Is it true that you shouldn't use olive oil for cooking as it has a lower smoke point and produces more carcinogens than other oils ?
We use rapeseed for cooking.

Smoke point is the easy bit.

You'll find a lot made of differences between olive oil, rapeseed oil and sunflower oil in their minor components and how they are affected by cooking including aldehydes, polyphenols, carotenoids and vitamin E. Very little of this (and possibly none) is supported by real-world observation of long-term beneficial or harmful effects, because the relevant studies haven't been done.

PS: Smoke point of cooking oil is one of the plotlines in Arthur Hailey's Hotel!

We use rapeseed for cooking.

I think that is mainly relevant to deep and shallow frying, i.e. using significant amounts of oil at high temperature. I don't think it matters for 'pan frying', e.g. brushing olive oil on steak and cooking it in a pan at very high temperature. I would not use olive oil to oil a baking tray when cooking something in the oven, not because of a health concern but because oilve oil hardens and bonds to the metal forming a coating akin to plastic, which is very difficult to remove.

Extra virgin olive oil is only suitable for relatively low temperature cooking, e.g. to saute ingredients for a pasta sauce, and I think the expensive high quality extra virgin olive oils should not be used to cook with at all.

Rapeseed oil is good enough for cooking.
EV Olive oil as a dressing.
We only use a tablespoon for chips as we use an air-frier.
