South India doesn't cook on one oil. Kerala reaches for coconut, Tamil Nadu leans on sesame (gingelly), and Andhra Pradesh and Karnataka use groundnut oil as an everyday base. If you're searching for the best oil for South Indian food, the honest starting point isn't a single winner, it's knowing which of these three oils your specific dish and region actually calls for.
Quick Answer
South Indian cooking traditionally uses three oils depending on region and dish: coconut oil for Kerala and coastal cuisine, sesame (gingelly) oil for Tamil Nadu tempering and pickles, and groundnut oil as an everyday base across Andhra Pradesh, Telangana, and Karnataka.

Top Picks for South Indian Cooking
-
Nothing To Hide's cold-pressed range. Because South Indian cooking genuinely needs more than one oil, Nothing To Hide's coconut, sesame, and groundnut oils cover all three regional staples in one cold-pressed range, dispensed through a spray bottle or smart measuring bottle for quantity control across whichever oil a dish calls for.
-
Cold-pressed coconut oil (general). The defining oil of Kerala cuisine, also foundational to coastal Karnataka and Tamil Nadu cooking.
-
Cold-pressed sesame/gingelly oil (general). Central to Tamil Nadu's pickle and tempering traditions, also used across Andhra Pradesh.
-
Cold-pressed groundnut oil (general). The everyday base oil across Andhra Pradesh, Telangana, and Karnataka kitchens.
-
Two Brothers and Anveshan. Wood-pressed and kachi ghani-style cold-pressed brands with visibility across coconut, sesame, and groundnut variants.
-
Idhayam. A long-established South Indian name particularly associated with sesame (gingelly) oil.
None of these is the single correct choice for every South Indian kitchen. The right oil depends on the specific dish, region, and whether a household keeps one primary oil or rotates by recipe, which is the more traditional approach.
Coconut Oil: The Foundation of Kerala Cooking
Coconut oil isn't a flavour option in Kerala cuisine; it's structural. Fish curries, coconut-based gravies, tempered curry leaves, and much of the state's everyday cooking are built around it.
A few practical notes on cooking with coconut oil:
-
It solidifies below room temperature. Cold-pressed coconut oil turning solid or cloudy in cooler weather is a natural sign of minimal processing, not spoilage.
-
Its fat is predominantly saturated, largely medium-chain triglycerides, which makes it comparatively heat-stable, though it should still be used as part of a varied diet rather than the sole cooking fat, in line with general ICMR-NIN guidance to use a variety of oils.
-
Flavour matters as much as function. Outside coconut-forward regional cuisine, coconut oil's distinct taste can be intrusive in dishes not built around it, which is why South Indian cooking traditionally reserves it for the dishes where it belongs, rather than using it universally.
Nothing To Hide's cold-pressed coconut oil is available in the same spray and measuring bottle formats as the rest of the range.
Sesame (Gingelly) Oil: Tamil Nadu's "Good Oil"
In Tamil Nadu, sesame oil is called nalla ennai, literally "good oil," a name that reflects how central it is to the region's cooking. It shows up across three main uses:
-
Tempering (tadka/thalippu): A quick high-heat step for dal and rice dishes.
-
Pickling: Many South Indian achaar recipes use sesame oil both for flavour and as a traditional preserving medium for pickled vegetables.
-
Finishing rice dishes: Tamarind rice (puli sadam) and sesame rice (ellu sadam) both use sesame oil as a defining flavour element, not just a cooking medium.
Sesame oil has a moderate smoke point, generally lower than refined oils, so it's better suited to tempering and finishing than sustained high-heat frying. Its natural antioxidants make it comparatively resistant to oxidative degradation even at a lower smoke point, which is part of why it has held its traditional role in Tamil and Andhra kitchens for centuries.
Nothing To Hide's cold-pressed sesame oil fits this same traditional role.
Groundnut Oil: The Everyday Base Across Andhra, Telangana, and Karnataka
Where coconut and sesame oil are often dish-specific, groundnut oil functions more like an everyday base across Andhra Pradesh, Telangana, and Karnataka kitchens, used in dishes from gongura pachadi to gutti vankaya curry and various Chettinad-style preparations.
Why it works as a daily oil:
-
A comparatively mild flavour that doesn't dominate a dish the way mustard or sesame oil would.
-
A smoke point of 160 to 170°C (Nothing To Hide's cold-pressed groundnut oil), suitable for everyday sautéing, tempering, and shallow frying.
-
A long regional history, with deep culinary roots across South Indian states beyond just Andhra and Karnataka.
Nothing To Hide's cold-pressed groundnut oil fills this everyday role in the range.

Quantity Still Matters, Whichever Oil Fits the Dish
South Indian cooking often uses smaller, more frequent quantities of oil, a spoonful for tempering here, a light coat for a dosa there, which makes it especially easy to lose track of total daily oil use. ICMR-NIN's guidance puts visible fat (cooking oil added during preparation) at roughly 20 to 50 grams per person per day, depending on gender and activity level.
Nothing To Hide's smart measuring bottle shows the quantity before it reaches the pan, useful for a tempering step that's meant to be a spoonful rather than a guess. The spray bottle is particularly suited to dosa and idli-pan greasing, where a thin, even layer matters more than a heavy pour. Nothing To Hide's oil calorie calculator can help translate a measured quantity into an approximate calorie figure across a full South Indian meal built from multiple small oil uses.
Building a South Indian Kitchen Oil Rotation
-
Coconut oil for curries, fish preparations, and any dish where its flavour is traditional to the recipe.
-
Sesame oil for tempering, pickling, and finishing rice dishes, particularly in Tamil and Andhra cooking.
-
Groundnut oil as the everyday base for dishes where a milder flavour is preferred.
-
A spray format kept aside for dosa, idli, and tawa greasing, regardless of which oil is loaded that week.
Households transitioning from a single refined oil to a proper regional rotation can start with Nothing To Hide's starter kit to try all three before committing to full bottles; the cooking oil glossary is a useful reference for terms like gingelly, cold-pressed, and smoke point.
Frequently Asked Questions
What oil is best for South Indian cooking?
There isn't one universal answer; South Indian cuisine traditionally uses three oils depending on region: coconut oil in Kerala and coastal areas, sesame (gingelly) oil in Tamil Nadu and Andhra Pradesh, and groundnut oil as an everyday base in Andhra Pradesh, Telangana, and Karnataka.
Why does Kerala food use so much coconut oil?
Coconut oil is foundational to Kerala's culinary identity, used in curries, fish and seafood gravies, and everyday tempering. Its comparatively heat-stable saturated fat profile and distinct flavour are both part of why it has remained central to the region's cooking.
What is gingelly oil?
Gingelly oil is another name for sesame oil, commonly used in Tamil Nadu and Andhra Pradesh cooking for tempering, pickling, and finishing rice dishes. In Tamil, it's called nalla ennai, meaning "good oil."
Is groundnut oil used in South Indian cooking?
Yes. Groundnut oil is an everyday base oil across Andhra Pradesh, Telangana, and Karnataka, used in dishes ranging from gongura pachadi to Chettinad-style preparations, valued for its mild flavour and moderate smoke point.
Can I use one oil for all South Indian cooking?
You can, but rotating oils by region and dish, coconut for Kerala-style curries, sesame for Tamil tempering and pickles, groundnut for everyday cooking, reflects how South Indian kitchens have traditionally worked, and lets each dish's characteristic flavour come through.
Is coconut oil solidifying a sign it's spoiled?
No. Cold-pressed coconut oil solidifying or turning cloudy below room temperature is a natural property of minimally processed coconut oil, not a quality or spoilage issue.
What oil is used for South Indian pickles?
Sesame oil is the traditional choice for South Indian achaar and pickle recipes, valued both for its flavour contribution and its long-standing role as a preserving medium.
Where can I see Nothing To Hide's South Indian oils?
Coconut, sesame, and groundnut oil are all available in the cold-pressed oils collection.
