How to Cook, Store, and Taste Extra Virgin Olive Oil
Extra virgin olive oil (EVOO) isn’t just an ingredient - it’s a culinary powerhouse. From enhancing the flavor of your dishes to offering a treasure trove of health benefits, EVOO is often referred to as "liquid gold." But how do you choose the right one, store it properly, and integrate it seamlessly into your cooking routine? The answer lies in understanding the science, history, and culinary versatility of this remarkable oil.
In a fascinating discussion featuring Dr. Joanna McMillan, a PhD-qualified nutritional scientist, and Chef Tom Hitchcock, an executive chef specializing in Southeast Asian cuisine, we dive deep into the world of extra virgin olive oil. This article distills their expertise into actionable insights for anyone passionate about premium culinary experiences. Whether you’re a home cook or a seasoned chef, this guide will transform the way you think about - and use - EVOO.
What Makes Extra Virgin Olive Oil Special?
At its essence, extra virgin olive oil is simply the juice of fresh olives. Unlike refined oils, which often undergo extensive chemical processing, EVOO is unrefined, meaning it retains all its natural compounds, including polyphenols, monounsaturated fats, and vitamin E. Not only do these components contribute to its robust flavor, but they also provide substantial health benefits.
Key Characteristics of EVOO:
- Freshness Matters: EVOO doesn’t age like wine. Over time, it can lose its quality and health benefits. Look for olive oil with a harvest date and aim to use it within 6 weeks after opening.
- Polyphenols’ Role: These plant-derived compounds give EVOO its distinctive peppery sensation and serve as powerful antioxidants.
- Stability Under Heat: Contrary to popular myths, EVOO is one of the most stable oils for cooking, even at high temperatures, thanks to its monounsaturated fats and protective polyphenols.
Debunking Myths: Can You Cook with Extra Virgin Olive Oil?
One of the most persistent myths about EVOO is that it shouldn’t be used for cooking due to its lower smoke point. However, science proves otherwise. EVOO is not only safe to cook with but also highly beneficial.
Why EVOO Excels in Cooking:
- Heat Stability: Monounsaturated fats in EVOO are highly stable and resistant to oxidation, even at high temperatures.
- Nutrient Preservation: Polyphenols and vitamin E protect the oil during cooking, reducing the production of potentially harmful compounds.
- Enhanced Flavor: Heating EVOO can deepen its nutty, caramelized notes, adding complexity to your dishes.
Chef Tom Hitchcock, who incorporates EVOO into Southeast Asian cuisine, shared an innovative technique: heating EVOO to 260°F (126°C) to caramelize its polyphenols, resulting in a brown butter-like flavor. EVOO’s versatility extends to frying, sautéing, and even baking, making it a true multitasker in the kitchen.
The Art of Choosing and Storing EVOO
Not all olive oils are created equal. Choosing high-quality EVOO involves understanding its origin, harvest time, and production methods.
How to Select the Perfect EVOO:
- Look for "Extra Virgin": This designation indicates the oil is unrefined and meets strict quality standards.
- Check the Harvest Date: Freshness is key. Opt for oils harvested within the last year.
- Prioritize Local Oils: Australian EVOO, for example, is known for its stringent quality controls and fresh, robust flavors.
- Assess Packaging: Choose oils stored in dark glass bottles or casks to protect against light and oxidation.
Proper Storage Tips:
- Keep It Cool and Dark: Store EVOO in a pantry away from light, heat, and air. Avoid placing it near your stove.
- Use It Quickly: Once opened, aim to finish a bottle within 6 weeks to preserve its flavor and health benefits.
- Opt for Sustainable Solutions: Many producers now offer refillable bottles or casks to minimize waste.
Culinary Uses: From Star Ingredient to Subtle Accents
EVOO’s versatility is unmatched - it can be the hero of a dish or a supporting character that enhances other flavors. Chef Tom Hitchcock highlighted several creative ways to use EVOO:
- As the Star Ingredient: Tom’s olive oil sorbet is an extraordinary example of EVOO’s potential. Achieving the perfect balance of flavor and texture requires skill but results in a unique dessert that’s both refreshing and indulgent.
- In Fusion Dishes: By experimenting with EVOO in green curries and Southeast Asian broths, Tom discovered how its peppery and fruity notes can complement bold spices.
- For Infusions: Flavored EVOOs, infused with ingredients like kaffir lime leaves or rose petals, add layers of complexity to both savory and sweet dishes.
- In Baking: Replace butter or other oils with EVOO in cakes and muffins for a rich depth of flavor and added moisture.
- Raw Applications: Use light or medium EVOOs for drizzling over salads, soups, or roasted vegetables to let their natural flavors shine.
Health Benefits Backed by Science
EVOO is more than a flavor enhancer - it’s a boon for your health. Dr. Joanna McMillan explained how its unique composition impacts various aspects of well-being:
- Heart Health: Rich in monounsaturated fats and polyphenols, EVOO supports cardiovascular health by reducing inflammation and improving cholesterol levels.
- Brain Function: High polyphenol intake has been linked to better cognitive performance and a reduced risk of neurodegenerative diseases.
- Weight Management: EVOO helps regulate appetite by promoting satiety and reducing the likelihood of overeating.
- Gut Health: Polyphenols act as prebiotics, fostering a healthy gut microbiome.
- Skin Benefits: The vitamin E in EVOO contributes to skin elasticity and hydration.
Sustainability in Olive Oil Production
EVOO is inherently sustainable. Olive trees require minimal resources to thrive and can live for centuries, reducing the need for frequent replanting. Additionally, producers are finding innovative ways to use every part of the olive:
- Pomace and Pit: These byproducts are repurposed as biofuel, livestock feed, or even supplements.
- Olive Leaves: Used for teas and extracts, olive leaves provide additional health benefits.
As global awareness of sustainability grows, EVOO producers are leading the charge with eco-friendly practices and recyclable packaging.
Key Takeaways
- Freshness is Paramount: Always check the harvest date and aim to use EVOO within 6 weeks of opening.
- Cooking with EVOO: It’s safe, stable, and enhances the flavor and nutrition of your dishes.
- Versatility: EVOO shines across cuisines, from Mediterranean to Southeast Asian, and can be used in desserts, marinades, and even broths.
- Health Benefits: Daily consumption of 2–3 tablespoons of EVOO supports heart, brain, and gut health.
- Sustainability: Olive oil production is eco-friendly, with minimal waste and innovative uses for byproducts.
- Explore Flavor Profiles: Different olive varieties yield unique oils. Experiment to find your favorite.
