Cooking Techniques
Raw Mustard Oil as a Finishing Seasoning
In most of India mustard oil is a cooking fat. In Assam it is also a condiment — and the difference is the entire pitika technique.
01
The story
Every Assamese household eats pitika, and every Assamese household is quietly certain that theirs is correct and the neighbours’ is not. The disagreements are about the ratio of mustard oil to potato and whether the onion is chopped or crushed.
I include it here because it is the clearest demonstration of a principle that runs through the whole cuisine: raw mustard oil used as a finishing seasoning rather than a cooking fat. Once you have understood pitika, half the vegetarian repertoire opens up.

About the dish
- Origin
- Everyday home cooking, eaten with rice at almost any meal.
- Region
- Assam, with equivalents across the Northeast and eastern India.
- Cultural significance
- Pitika is a method, not a single dish — anything boiled or roasted and then mashed with raw mustard oil qualifies. Potato is simply the most common.
- Flavour profile
- Sharp, pungent and clean. The mustard oil is meant to catch at the back of the throat.

Ingredients
Everything
- 500 g potatoes floury variety, boiled whole in their skins
- 2–3 tbsp raw mustard oil unheated — this is the point of the dish
- 1 small onion chopped very fine
- 2 green chillies chopped fine
- to taste salt
- a handful coriander leaves chopped
Substitutions & notes
- Roasted aubergine (bengena pitika), boiled fish (masor pitika) or blanched greens (xaak pitika) all follow exactly this method.
- If raw mustard oil is too pungent for you, warm it gently and cool it before using. You lose some of the character but keep the dish.

Method
-
Step 01
Boil
- Boil the potatoes whole and in their skins until a knife slides through with no resistance. Whole and unpeeled means they do not waterlog.
- Drain and leave them until they are cool enough to handle but still warm. Warm potato takes the oil; cold potato does not.
-
Step 02
Mash
- Peel and mash by hand, with a fork or the heel of your palm. Never a food processor — you want texture, and you will get glue.
-
Step 03
Season
- Add the salt first and mix it through. Then the mustard oil, poured over and folded in until it disappears.
- Fold in the onion, chilli and coriander last so they stay distinct rather than dissolving into the mash.
-
Step 04
Finish
- Taste. It should be assertively salty and pungent on its own, because it will be eaten with plain rice.
- Shape into a rough mound and serve at room temperature.

Palateful notes
What I learned
- Season the potato before adding fat. Salt dissolves in the moisture that is still there; add oil first and it never distributes properly.
- Warm, not hot, and never cold. The window matters more than the recipe.
- Mustard oil is a seasoning here, not a cooking medium. Heating it defeats the entire dish.
Common mistakes
- Over-mashing into a purée.
- Under-salting because it tastes strong on the spoon — it is not eaten on a spoon.
- Adding the onion early, so it weeps and turns the mash wet.
Variations
- A little crushed ginger is common in upper Assam.
- Bengena pitika — the same treatment for a fire-roasted aubergine — is arguably the better dish.
