Quick answer
Groundnut (peanut) oil, called singtel in Gujarati, has long been the everyday cooking oil of Saurashtra, one of India's major groundnut-growing regions, so many Kathiawadi pickles are traditionally made with it. Its mild, nutty taste lets mango and spices lead. Because recipes differ, always read the ingredient list to see which oil a particular jar uses.
What people mean by groundnut oil pickle
When someone searches for a groundnut oil pickle, they usually mean a pickle in the Gujarati or Kathiawadi style, where raw mango or other vegetables sit in a spiced masala under a layer of peanut oil rather than mustard or sesame oil.
The oil is not a background detail. In a traditional achar it seals the pieces from air, carries the flavour of the spices, and shapes how the pickle tastes. Changing the oil changes the pickle, which is why people who grew up with one style often notice immediately when a jar uses another.
Why Saurashtra kitchens reach for groundnut oil
Saurashtra, the Kathiawad peninsula of Gujarat, is one of India's best-known groundnut regions. For generations, peanuts (singdana) have been grown there and pressed locally, and groundnut oil has been the oil of daily cooking, from tadka for dal to frying farsan.
Pickles naturally used the oil the kitchen already trusted. A family pressing or buying groundnut oil for the whole year would use the same oil for its keri achar, gunda pickle, and methia masala. That habit, more than any rule, is how groundnut oil became linked with Gujarati pickles.
What groundnut oil does in the jar
- Forms the oil layer that keeps air and moisture away from the pieces.
- Has a mild, gently nutty taste that lets mango, mustard, and chilli lead.
- Carries the aroma of hing, fenugreek, and split mustard through the whole jar.
- Coats the masala so it stays moist rather than drying out.
- Can turn cloudy or partly solid in cold weather, which is natural.
Groundnut, mustard, and sesame oil compared
- Groundnut oil — mild and nutty; the spices and mango dominate. Traditional in many Gujarati and Kathiawadi homes.
- Mustard oil — pungent and sharp, with its own heat. Traditional in many North and East Indian pickles.
- Sesame (til or gingelly) oil — deeper, toasty flavour. Common in many South Indian pickles.
- What they share — each forms the protective layer that keeps pieces covered; none is simply better than the others.
- How to choose — by the regional taste you prefer and by any allergy in the family.
Cold-pressed, filtered, and refined
Groundnut oil reaches kitchens in a few forms. Cold-pressed or wood-pressed oil (often called ghani or kachi ghani oil) is pressed without high heat and keeps a stronger peanut aroma and a deeper golden colour. Filtered oil is pressed and then filtered to remove fine particles. Refined oil is processed further, which makes it lighter in colour and more neutral in taste.
Pressed oil adds a noticeable nutty note; refined oil lets the spices speak almost entirely on their own.
How oil goes into a Gujarati pickle
In a typical Kathiawadi recipe, the raw mango is first salted with turmeric, drained, and dried. The masala of split mustard, fenugreek, chilli, hing, and salt is then mixed into the pieces, and the oil goes in last.
Many recipes heat the oil and let it cool completely before pouring it over, while others use it as it is. Either way, the oil must be cool and the jar completely dry. Enough oil is added to cover the pieces, and the level is checked again after a few days because the masala soaks some of it up.
How to read the oil on a pickle label
- Find the ingredient list rather than relying on the front of the pack or a general description.
- Look for the oil named specifically, such as groundnut oil, mustard oil, or sesame oil.
- Treat 'edible vegetable oil' or 'refined vegetable oil' as a generic term that does not tell you the source.
- Check whether a blend is listed; blended oils should name each oil.
- Read the allergen statement if there is one, and look for peanut in particular.
- Note the FSSAI licence number and the storage instructions printed on the jar.
Checking The Pickle Affair jars
Our Homemade Mango Pickle, Katka Keri, and Gunda Keri are made in the traditional Kathiawadi style, in small batches and with no synthetic colours. Each product page lists its ingredients, and that list, along with the label on the jar, is the place to confirm which oil is used.
We would rather you check than assume. Recipes and sourcing can be updated over time, and the label on the jar in your hand is always the most reliable source. The Pickle Affair is a brand of Arham Foods, packed in Maharashtra under FSSAI licence 21521053000490.
Peanut allergy: a clear rule
Anyone with a peanut allergy should avoid pickles made with groundnut oil and should read every label carefully, every time. Do not rely on the style of a pickle or on what a family recipe usually contains; check the ingredient list and any allergen statement.
When serving guests, mention the oil if you know it, and use a separate spoon for each jar.
Living with a groundnut oil pickle
Groundnut oil is known for turning cloudy or partly solid in cold weather or in the fridge. The layer looks pale and waxy and melts back to clear oil at room temperature. This is a physical change, not spoilage.
Keep the pieces under the oil, use only a dry spoon, and close the lid firmly. If the oil ever smells stale, sharp, or paint-like, or if there is fuzzy growth, bubbles, or a bulging lid, discard the jar rather than tasting it.
Using the oil left at the end
When the pieces are finished, the spiced oil left behind is full of flavour. Many Gujarati homes use a spoonful to brush on thepla or rotli, mix into curd rice, toss with boiled potatoes, or drizzle over khichdi.
Use it while it still smells fresh and keep it covered. The oil carries the same allergy caution as the pickle.

Why do Gujarati pickles use groundnut oil?
Saurashtra is a major groundnut region, and groundnut oil has long been the everyday cooking oil there, so many traditional pickles use it.
Is groundnut oil pickle safe for a peanut allergy?
No. Anyone with a peanut allergy should avoid pickles made with groundnut oil and check every label carefully.
Groundnut or mustard oil: which is better for pickle?
Neither is better. Groundnut oil is mild and traditional in Gujarat; mustard oil is pungent and traditional in the north and east.
How do I know which oil a pickle uses?
Read the ingredient list on the jar or product page. A clear label names the oil rather than saying only 'vegetable oil'.
Why does groundnut oil in pickle turn cloudy?
Some fats in groundnut oil solidify in the cold. The oil clears again at room temperature and is harmless.
Is cold-pressed groundnut oil different in pickle?
Yes. Pressed oil keeps more peanut aroma and colour, while refined oil is more neutral and lets the spices lead.
Can I reuse leftover groundnut pickle oil?
Yes, as a seasoning for thepla, curd rice, or potatoes, as long as it still smells fresh and is kept covered.
Does The Pickle Affair use synthetic colours?
No. Colour comes from the spices, turmeric, chilli, and mango themselves.
Who makes The Pickle Affair pickles?
The Pickle Affair is a brand of Arham Foods, packed in Maharashtra under FSSAI licence 21521053000490.
Conclusion
Groundnut oil is part of why traditional Kathiawadi pickle tastes mild, nutty, and spice-forward. Enjoy the tradition, but let the label on each jar tell you which oil it actually uses, especially if anyone at your table has a peanut allergy.
