1. Extra Virgin Olive Oil (EVOO)
What to buy: Extra virgin olive oil (EVOO) is non-negotiable. It's the primary cooking fat and flavouring in the Med, so invest in as high-quality one as you can afford.
Look for oils in dark glass bottles or tins, as sunlight degrades quality. Also, look for harvest dates within the past year (should be on the back label of the bottle). You don't need the most expensive brand, but avoid the cheaper options.
Can you cook with olive oil?
High-quality EVOO can be used for cooking at moderate temperatures (up to 190°C/375°F), though some of the more delicate nutrients ("polyphenols") degrade with heat.
For this reason, many Mediterranean cooks use a moderately-priced EVOO for everyday cooking and reserve their finest, most peppery oils for "finishing" dishes. Like drizzling over salads, soups, grilled vegetables, and bread.
Storage: Keep olive oil in a cool, dark place away from heat and sunlight. A pantry cupboard works perfectly. Properly stored, EVOO maintains quality for 12-18 months, though fresher is generally better.
Nutrition: EVOO is rich in monounsaturated fats that lower the 'bad' LDL cholesterol while maintaining (or even raising) beneficial HDL cholesterol.
This is the opposite of saturated fats, which raise both types of cholesterol, which makes EVOO particularly protective for cardiovascular health.
EVOO is also packed with polyphenols and vitamin E. These are powerful antioxidants that reduce oxidative stress and chronic inflammation, protect blood vessels, and prevent blood clots.
This potentially reduces the risk of heart disease, age-related cognitive decline, and certain cancers.
How to use it: Drizzle on salads, finish soups and stews with it, use it for sautéing vegetables, and roast potatoes and chicken in it.
Don't be shy, Mediterranean cooking uses olive oil liberally. A proper Greek salad gets a generous glug, not a quick drizzle.
Start by simply replacing butter or vegetable oil with EVOO when making scrambled eggs, sautéing vegetables, or dressing your morning avocado toast.
