The original North Indian cooking oil — pungent, bold, and alive. Cold pressed without heat at the first pressing (Kachi Ghani). The highest Omega-3 content of any common cooking oil, with allyl isothiocyanate that gives mustard oil its irreplaceable character.
No other common cooking oil provides the Omega-3 to Omega-6 ratio that mustard oil does — making it one of the healthiest choices for daily cooking.
The ALA Omega-3 content in mustard oil is unmatched among commonly used cooking oils — and unlike flaxseed oil, mustard oil can be used for cooking.

Yes — mustard oil has been used as a cooking oil across North India, Bangladesh, and Pakistan for thousands of years. The FDA ban in the USA on mustard oil as cooking oil is based on studies from the 1970s using very high doses of erucic acid in rats. Indian regulatory bodies (FSSAI) permit mustard oil as a cooking oil, and population studies show no increased health risk in mustard-oil-consuming regions.
Kachi Ghani (literally 'raw press') refers to oil extracted in the first cold pressing of mustard seeds without pre-heating them. This preserves the maximum pungency, Omega-3 content, and allyl isothiocyanate. Pakki Ghani (second press) uses pre-heated seeds and produces a milder, nutritionally inferior oil.
Allyl isothiocyanate — the volatile compound responsible for mustard oil's characteristic pungency — is only present in cold-pressed Kachi Ghani oil. Refined mustard oil is deodorised and loses this compound. The pungency is not just flavour — it is an indicator of nutritional quality.
Yes — mustard oil has one of the highest smoke points among vegetable oils at approximately 250°C, making it excellent for deep frying. The pungency largely dissipates at high temperatures, leaving a distinctive cooked flavour.
We test for erucic acid content in every batch. Our mustard oil meets FSSAI standards for food-grade mustard oil (erucic acid below 5% for consumer use). Full lab report available on request.
