How to Use Cooking Oils by Dish: Secrets You Didn’t Know

One Bottle of Oil Can Change Your Table.

• You will be able to choose the perfect cooking oil for your dishes.
• Learn how to preserve flavor and health by understanding oil smoke points.
• Keep your oils fresh longer with proper storage techniques.

The Start of Every Dish: Understanding Cooking Oils

The crisp sizzle that fills the kitchen. The moment oil coats the heated pan and the star ingredient takes its place—this is where every delicious dish begins. We put great care into selecting fresh ingredients, but often forget the crucial role of cooking oil.

“Aren’t all oils basically the same?” Not at all. The type of oil and how you use it can change the taste, aroma, texture of your food, and even your family’s health. This article reveals the hidden story of oils that will upgrade your kitchen.

Chapter 1: The Oil’s Cry, The Secret of the ‘Smoke Point’

Every oil has a critical temperature it can withstand—its smoke point. This is the temperature at which the oil starts to smoke when heated.

Exceeding this temperature destroys beneficial components and can produce carcinogens like ‘benzo[a]pyrene.’ The flavor turns bitter, and valuable nutrients vanish. Therefore, understanding each oil’s characteristics and choosing the right cooking method is essential.

Chapter 2: Heroes of High Heat – Oils for Frying and Stir-Frying

Some oils have high smoke points that preserve the best flavors even under intense heat. They are the kitchen heroes responsible for the crispiness of tonkatsu and the crunch of stir-fried shredded potatoes.

Who Are the High-Heat Specialists?

• Avocado Oil: Smoke point 270°C. The highest among cooking oils, safe for any high-heat cooking.
• Sunflower Seed Oil: Smoke point 250°C. Mild aroma, versatile for any dish.
• Canola Oil: Smoke point 240°C. Clean taste, great for frying and pan-frying.
• Grape Seed Oil & Soybean Oil: Smoke points around 230°C and 220°C respectively. Familiar high-heat cooking partners.

Wait! Worried About GMOs?

Soy, corn, and canola are common genetically modified crops. If concerned, look for ‘Non-GMO’ labels when purchasing.

Real Story: Choosing the Perfect Oil for Tonkatsu

When I first fried tonkatsu, I naively used olive oil, and the kitchen filled with smoke while the cutlet burned black. The ideal frying temperature for tonkatsu is 160–170°C. Using canola or soybean oil, which can stably handle this temperature, results in perfectly cooked pork inside and golden, crispy batter.

Chapter 3: Guardians of Flavor – Oils for Dressings and Salads

Not all oils love heat. Some delicate oils reveal their true value when not heated. They add unique flavors, aromas, and rich nutrients to beautifully finish dishes.

The Low-Heat Avengers, Who Are They?

• Extra Virgin Olive Oil: Smoke point about 160–190°C. Its fresh grassy aroma pairs well with salad dressings and seasoned dishes.
• Perilla Oil & Sesame Oil: Smoke points about 160–170°C. Their nutty aroma is essential for finishing Korean dishes.

Real Story 1: ‘Caprese Salad’ Capturing the Italian Summer

Fresh tomatoes, soft mozzarella, and fragrant basil come together in Caprese salad. The final touch that turns this dish into art is extra virgin olive oil. The fresh scent and taste of freshly pressed olive oil envelop the natural flavors, delivering a Mediterranean summer in every bite.

Real Story 2: The Ultimate Nutty Flavor, ‘Perilla Oil Buckwheat Noodles’

Currently one of the trendiest noodles, perilla oil buckwheat noodles. The nutty aroma of perilla oil poured generously over well-cooked buckwheat noodles completes half the flavor. Perilla oil is the ‘king of omega-3’ among plant oils, containing over 60% omega-3 fatty acids.

Chapter 4: Balance for Your Body, Omega-3 vs Omega-6

Our body’s fatty acids require balance between ‘omega-3’ and ‘omega-6.’ Omega-3 suppresses inflammation, while excessive omega-6 can promote it.

The World Health Organization (WHO) recommends an ideal intake ratio of omega-6 : omega-3 = within 4:1, but modern diets can reach 20:1. This imbalance may cause chronic diseases. Reduce corn and soybean oil use, and increase intake of omega-3 rich foods like perilla oil, canola oil, and oily fish to restore healthy balance.

Checklist for Choosing the Right Cooking Oil for Your Dish

1. What dish are you making?: Frying/stir-frying or salad/dressing?
2. Check the smoke point: For high-heat cooking, choose oils with smoke points above 220°C.
3. Consider aroma and flavor: For preserving natural ingredient flavors, choose mild oils (canola, grape seed). To add richness, choose aromatic oils (olive, perilla).
4. Think about health: Add omega-3 rich oils like perilla and canola to balance fatty acids.
5. Check storage requirements: Confirm if the oil is prone to rancidity and whether it needs refrigeration.

Chapter 5: Wisdom to Protect Your Oil – Proper Storage

No matter how good the oil is, improper storage causes spoilage. The biggest enemies of oil are light, heat, and air.

1. Store in a cool, dark place: Avoid next to the stove. A dark, cool cupboard is ideal.
2. Always tightly close the lid: Air exposure causes rancidity.
3. Refrigerate perilla oil: Rich in omega-3, it spoils quickly and should be refrigerated and consumed promptly.
4. Can you reuse cooking oil?: You can reuse frying oil once or twice after straining debris, but smoke point lowers, so minimize reuse.

Conclusion

• Remember the smoke point: Choosing the right oil for your cooking method is the first step to great taste and health.
• Respect each oil’s role: Use avocado or canola oil for high heat, olive or perilla oil for low heat to maximize their strengths.
• Balance your intake: Consider omega-3 and omega-6 ratios for a healthy diet.
