Whatever your tastes, and budget, we’ve found an olive oil for you.

Extra virgin olive oil recipes

Our olive oil drizzled ice cream with balsamic strawberries recipe

To get more from our Best Buy olive oil at your summer soiree (and create a talking point), why not try making this different dessert.

We tried it with vanilla ice cream, balsamic vinegar and strawberries, and thought it was a delightful savoury twist to a dessert classic. If you have a really sweet tooth it might not be for you, though.

The oil gives both an initial green hit and a lingering peppery finish, while the balsamic vinegar adds a caramelised sensation to the strawberries. It even went well with vegan ice cream, Swedish Glace. Just make sure you use good quality vanilla ice cream, extra virgin olive oil and balsamic vinegar.

olive oil drizzled ice cream with balsamic strawberries

You'll need, per serving:

  • Two scoops of vanilla ice cream
  • Two teaspoons of extra virgin olive oil
  • A handful of fresh strawberries
  • One tablespoon of balsamic vinegar
  • One teaspoon of caster sugar


  1. Cut the strawberries into quarters and place them in a bowl or container with a wide base, so the marinade doesn’t pool at the bottom.
  2. Add the balsamic vinegar and caster sugar. Make sure the strawberries are well coated. Cover and leave them to marinate in the fridge for an hour.
  3. Place the ice cream into bowls and drizzle with the extra virgin olive oil. As the oil cools it will thicken.
  4. Top with the marinated strawberries and serve.

Which? members also get access to our exclusive salsa verde recipe from food expert Sam Rosen-Nash. It's a great way of using a quality extra virgin olive oil, and would make the perfect steak marinade.

How to shop savvy

We asked our experts to cut through the jargon often used on the side of extra virgin olive oils. Here's what they had to say:

Check the best before date

Olive oils are at their best when young and fresh, so look out for the best before date. This can be a better indicator than a production date. This is because the olives can be picked months before they are processed into an oil.

Don't pay more for 'cold-pressed'

Don’t be duped by trendy terms. ‘Cold-pressed’ and 'cold-obtained' are two that often appear, but all extra virgin olive oils, by their very name, are picked, processed and filtered cold. They couldn't be called 'extra virgin' if not.

Or 'hand-picked'

‘Hand-picked’ is another one you’ll see. But as it takes roughly 2.5kg of olives to make a 500ml bottle, all oils made on a large scale will use machinery in the picking process. This could be in the form of mechanical whiskers that shake the branches of olive trees to release the fruit before they are picked by hand from the floor, for example.

Filtered or unfiltered doesn't matter

Whether an oil is labelled as filtered or unfiltered doesn’t affect quality. It's an optional, additional step of passing it through cotton gauze to catch sediment – but this is for looks, not for taste. Unfiltered oil is just as good, but could have some cloudiness or sediment at the bottom made up of tiny particles of olive fruit.

Should you cook with olive oil?

cooking with olive oil

Choosing which kind of oil to cook with depends largely on your own culinary preferences. But there’s no need to cook with premium extra virgin olive oils. Their quality is too high, and this is lost in the cooking process, according to our experts.

When you heat an extra virgin olive oil, it changes and its subtleties are lost. Plus, you can heat regular or even virgin olive oil to a higher temperature than an extra virgin olive oil.

Extra virgin vs virgin olive oils

Virgin olive oils must be obtained from olives solely by mechanical or other physical means. Chemical processes can be used with standard olive oils, which can alter aroma and taste.

The difference between virgin and extra virgin oils comes down to quality. Extra virgin is the best and has an acidity level of no more than 0.8% – this is the percentage of free fatty acids. For virgin oil, it’s no more than 2%.

The lower the acidity, the better the olives have been cared for while on the tree, and during harvesting and processing. Both oils should be able to pass an assessment by a tasting panel.

How we tested

We asked each supermarket to suggest a premium, top-of-the-range Italian extra virgin olive oil. We chose to test Italian over Spanish or Greek olive oil, as many of the big brands widely available in the UK are Italian.

Each oil was disguised before being tasted blind and then rated by our panel of experts. Each expert tasted the oils in a different order, before discussing their ratings and agreeing on the Best Buy olive oil.

The scores for each rating were weighted as follows:

  • Taste 40%
  • Aroma 25%
  • Balance 25%
  • Complexity 10%

Our experts were: 

  • Charles Carey oil importer for The Oil Merchant
  • Nancy Gilchrist Master of Wine, educator for both olive oil and wine
  • Dan Mortimer Former owner of gourmet delicatessen, Mortimer & Bennett
  • Sam Rosen-Nash Olive oil taster, The Purple Scallion, Food Sage
