Which Cooking Oil Should You Use for Different Dishes? A Practical Guide
Santosh BobadeShare
Choosing the right cooking oil is about more than flavour. The oil you use can influence the aroma, texture and overall quality of your food. Different oils have different fatty acid compositions, flavours and responses to heat, making some better suited to certain cooking methods than others.
In Indian kitchens, groundnut oil, mustard oil, sunflower oil, coconut oil and ghee are commonly used for different dishes. But how do you decide which one to use for deep frying, everyday tadka, curries, roasting or baking?
This guide explains the key factors to consider when selecting cooking oils and how to match them to your favourite dishes.
1. Understanding Cooking Oils: Smoke Point and Oxidative Stability
Before choosing an oil, it helps to understand two important concepts: smoke point and oxidative stability.
What is the smoke point?
The smoke point is the temperature at which an oil begins to produce visible smoke. When oil is heated excessively, it can break down, develop unpleasant flavours and release unwanted compounds.
However, smoke point alone does not determine whether an oil is suitable for a particular cooking method. The oil's composition, freshness, processing, cooking temperature and duration of heating also matter.
What is oxidative stability?
Oxidative stability refers to an oil's resistance to reacting with oxygen. Heat, air and repeated frying can accelerate oxidation and affect an oil's quality.
Oils rich in monounsaturated fatty acids, such as oleic acid, are generally more resistant to oxidation than oils containing higher proportions of polyunsaturated fatty acids. However, the overall stability also depends on the oil's composition, natural antioxidants, processing and storage.
The practical takeaway: Choose an oil that suits your cooking temperature, flavour preference and recipe. Avoid overheating any oil, and do not continue using oil that has deteriorated.
2. Deep Frying and High-Heat Cooking: Groundnut and Safflower Oil
Deep frying puris, pakoras, bhajiyas and cutlets requires oil that can withstand sustained heat. A common deep-frying temperature is approximately 175°C to 190°C, depending on the food and recipe.
Groundnut oil is widely used in Indian cooking because of its characteristic flavour and suitability for frying. It contains oleic acid and linoleic acid, although the proportions vary with the groundnut variety and processing method.
Groundnut oil can be a practical option for puris, pakoras, savoury snacks and other fried foods. Its suitability depends on the particular oil's quality and how it responds to heating.
Wood-pressed groundnut oil may appeal to people who prefer traditionally extracted oils and their characteristic aroma. However, its smoke point and frying performance should not be assumed to be identical to those of refined groundnut oil.
Best suited for: Puris, pakoras, bhajiyas, cutlets and selected shallow-frying recipes.
Safflower oil is another option for everyday cooking and frying. Its fatty acid composition varies: conventional safflower oil is often rich in linoleic acid, while specially developed high-oleic varieties contain more oleic acid.
This distinction matters because high-oleic safflower oil generally offers greater oxidative stability than conventional high-linoleic safflower oil.
For frying, check the product's intended use and suitability for high-temperature cooking rather than relying on the name of the oil alone.
Best suited for: Selected frying, roasting and sautéing applications, depending on the oil's formulation and product guidance.
3. Everyday Cooking, Tadka and Curries: Mustard and Sunflower Oil
Many Indian dishes require moderate heat for sautéing vegetables, tempering spices and preparing dals or curries. For these recipes, flavour is often just as important as heat tolerance.
Mustard oil is known for its distinctive pungent aroma and bold flavour. It is traditionally used in several regional Indian cuisines, particularly in dishes where its strong taste complements the other ingredients.
It can be used for vegetable preparations, fish curries, pickles and selected regional recipes, provided the product is intended for culinary use and complies with applicable food standards.
Mustard oil contains different fatty acids, including oleic acid and, depending on the variety, alpha-linolenic acid. Its nutritional composition varies, so avoid assuming that every mustard oil has the same fatty acid profile.
Best suited for: Regional curries, vegetable preparations, fish dishes and recipes that benefit from a distinctive mustard flavour.
Sunflower oil is commonly chosen for its relatively mild flavour. It allows herbs, spices and other ingredients to remain the focus of a dish.
Its fatty acid composition varies by variety. Conventional sunflower oil is generally rich in linoleic acid, while high-oleic sunflower oil contains more oleic acid and typically has greater oxidative stability.
Use the product's label to understand its intended cooking applications.
Best suited for: Everyday vegetable dishes, dal tadka, mild curries and sautéing.
4. Coconut Oil and Almond Oil: Flavourful Finishing and Speciality Cooking
Some oils are chosen as much for their distinctive flavour as for their cooking properties.
Coconut oil has a characteristic aroma and contains a high proportion of saturated fatty acids, particularly lauric acid. Its composition gives it different physical and cooking characteristics from oils rich in unsaturated fatty acids.
It is often used in South Indian and coastal cooking, where its flavour complements the ingredients.
Virgin or cold-pressed coconut oil may have a stronger coconut aroma, while refined varieties generally have a milder flavour. Their smoke points can differ depending on processing and product quality.
Best suited for: Coconut-based curries, vegetable stews, selected sautéing recipes and baking where coconut flavour is desirable.
Almond oil contains a high proportion of monounsaturated fats and may contain vitamin E and other minor components, depending on the product and processing.
Its suitability for cooking depends on whether it is specifically sold as an edible cooking oil. Products intended for cosmetic use should not be used in food preparation.
Edible almond oil can be used in dressings, marinades and finishing applications where its mild nutty flavour complements the dish. Follow the product's temperature and storage recommendations rather than assuming that every almond oil is suitable for high-heat cooking.
Best suited for: Salad dressings, finishing touches and selected baking recipes.
5. Roasting, Rotis and Traditional Sweets: Ghee
Ghee is an important ingredient in Indian cooking, valued for its rich aroma and characteristic flavour. It is commonly used for roasting spices, preparing traditional sweets and adding flavour to everyday meals.
Because clarification removes most of the water and milk solids, ghee generally has a relatively high smoke point compared with butter. Its exact smoke point can vary with its composition and quality.
Ghee is suitable for many sautéing, roasting and frying applications. However, a high smoke point does not mean that it cannot deteriorate when overheated.
A2 describes a particular type of beta-casein protein in milk; it does not, by itself, establish that ghee has a higher smoke point or is superior for high-temperature cooking. The cooking properties of ghee depend on the finished product rather than the A2 label alone.
Best suited for: Roasting spices, preparing rotis and parathas, making traditional sweets and adding a rich flavour to rice or khichdi.
As with all fats, use ghee in moderation as part of a balanced diet.
6. Wood-Pressed Oils vs. Refined Oils: What Should You Know?
Wood-pressed and refined oils differ in their extraction and processing methods. Understanding these differences can help you choose a product that suits your cooking preferences.
Wood-pressed oils are extracted mechanically using a traditional pressing method. Depending on the production process, they may retain more of the seed's characteristic aroma, flavour and certain naturally occurring minor components.
Their composition and quality can vary according to the raw material, extraction conditions, filtration and storage.
Wood-pressed does not automatically mean that an oil is suitable for every cooking temperature. Check the product's intended use and avoid prolonged overheating.
Refined oils
Refining can involve steps such as degumming, neutralisation, bleaching and deodorisation, depending on the oil and production process. These steps help remove impurities, reduce unwanted flavours and improve certain functional properties.
Refining can also reduce some naturally occurring minor compounds. However, it does not follow that all refined oils are unsafe or devoid of nutritional value. Properly produced refined oils that meet applicable food standards can be suitable for cooking.
Likewise, wood-pressed oils are not automatically free from contaminants or oxidation. Quality depends on the raw materials, processing, handling, packaging and storage.
How should you choose?
When selecting an oil, consider:
- Cooking method: Match the oil to the temperature and duration of cooking.
- Flavour: Choose an oil that complements the dish.
- Product information: Read the label, ingredients and storage instructions.
- Quality assurance: Look for reliable sourcing and verifiable quality information.
- Storage: Keep the oil tightly closed and away from direct sunlight and excessive heat.

7. How to Use Cooking Oil More Responsibly
Regardless of which oil you choose, everyday cooking practices make a difference.
- Avoid heating oil until it smokes.
- Use the amount required by the recipe.
- Keep oil away from moisture and food particles during storage.
- Store it in a tightly closed container in a cool, dark place.
- Avoid repeatedly heating and cooling the same frying oil.
- Discard oil that becomes unusually dark, thick, foamy or unpleasant in smell.
- Follow the product's storage instructions and use-by guidance.
Repeated frying can increase oil degradation. Filtering out food particles does not reverse oxidation or restore the oil's original quality. Therefore, avoid treating filtering or reheating as a way to make deteriorated oil safe again.
Conclusion
There is no single cooking oil that is best for every dish. Groundnut oil can be a useful option for frying, mustard oil adds a distinctive flavour to regional curries, sunflower oil suits recipes that benefit from a mild taste, coconut oil complements coconut-based dishes, and ghee brings a rich aroma to traditional cooking.
Safflower and almond oils can also have a place in the kitchen, depending on the product's composition and intended use.
The best choice depends on the cooking method, temperature, flavour, oil composition and product quality. Rather than relying on claims that one oil is universally superior, choose suitable oils, store them correctly and avoid repeated overheating.
