Yellow Mustard Seeds: How to Use Peela Sarso at Home
Yellow mustard seeds are used in Indian kitchens mainly for pickles, mustard pastes, kadhi and a gentle tempering — they are bigger, milder and more tangy than black mustard, so they season a dish without a sharp bite. Use them whole in hot oil for tadka, or soak and grind them into a smooth paste for achar and Bengali-style gravies.
Also known as: yellow mustard seeds are called peela sarso or safed sarso in Hindi, sarson across North India, and white mustard in English. When a recipe just says "mustard seeds" for a dal or sambar tadka, it usually means the small black ones — but for pickles and mustard paste, these yellow seeds are the ones you want.
What are yellow mustard seeds?
They are the round, pale-golden seeds of the mustard plant, noticeably larger than black mustard and much lighter in colour. On their own they taste mild and faintly sweet — the familiar sharp mustard flavour only wakes up once the seeds are crushed or soaked in liquid. That is exactly why they suit pickles and pastes, where the flavour is meant to build slowly over days rather than hit you in the first bite. ODM Yellow Mustard Seeds are clean, handpicked whole seeds with no artificial colours, no fillers and no preservatives.
Yellow or black mustard seeds: which one should you use?
| Yellow mustard (peela sarso) | Black mustard (rai) | |
|---|---|---|
| Size | Larger, round, pale gold | Small, dark brown to black |
| Flavour | Mild, tangy, slowly sharp | Pungent and nutty straight away |
| In hot oil | Pops slowly, stays mellow | Splutters fast, turns nutty |
| Best for | Pickles, mustard paste, kadhi, marinades | Tadka for dal, sabzi and chutney |
Most Indian kitchens keep both. If you cook a lot of eastern-Indian food, keep black mustard seeds for daily tempering and yellow ones for anything that needs a paste.
How to use yellow mustard seeds in Indian cooking
- Pickle masala: coarsely crush the seeds and mix with salt, turmeric, chilli and mustard oil for aam ka achar, nimbu achar or mirchi achar. Crushed seeds release flavour far better than whole ones in a pickle jar.
- Mustard paste for gravies: soak, grind and use for Bengali-style fish, potatoes or any sarson-based curry. A little goes a long way.
- Kadhi and besan curries: a spoon of whole seeds in the tempering gives kadhi its faint tang without extra heat.
- Everyday sabzi: excellent in cabbage, potato, pumpkin and raw banana sabzi, especially in eastern and coastal cooking.
- Panch phoron cooking: mustard is one of the five seeds in the Bengali blend — if you like this style, keep a jar of ODM Panchforan handy for a ready-made tempering.
- Marinades and dressings: crushed yellow mustard with lemon, salt and oil makes a quick homemade table mustard for sandwiches and salads.
How do you grind mustard seeds without bitterness?
Bitterness is the one complaint people have with mustard paste, and it is almost always a grinding problem, not a seed problem. Try this:
- Soak the seeds in water for 20 to 30 minutes before grinding.
- Grind with cold water, never warm — heat is what turns mustard bitter.
- Add a green chilli and a pinch of salt to the grinder; both help balance the taste.
- Grind in short bursts and stop as soon as the paste is smooth. Over-grinding heats the mixture.
- Let the paste rest for 10 minutes before cooking so the sharpness settles.
How should you store yellow mustard seeds?
Whole seeds are hardy. Keep them in an airtight steel or glass jar, away from the heat of the stove and out of direct sunlight, and always use a dry spoon — moisture is the one thing that spoils them. Stored this way, whole seeds hold their aroma comfortably for a year. Fresh mustard paste is a different story: refrigerate it and use it within two to three days.
FAQ
Are yellow mustard seeds and rai the same?
No. Rai is the small black or dark brown mustard seed with an immediate pungency, while yellow mustard (peela sarso) is larger, paler and much milder. They are not interchangeable in a tadka, though many pickle recipes happily use both.
Can I use yellow mustard seeds for tadka?
Yes, but expect a gentler result. They take a little longer to pop and give a mellow, tangy note rather than the sharp crackle of rai. For dal and sambar, black mustard is the better choice.
Why does my mustard paste taste bitter?
Usually because it was ground with warm water or ground for too long, both of which heat the seeds. Soak first, use cold water, add a green chilli and a pinch of salt, and grind in short bursts.
