Most people switch in one go. They order three or four bottles, pour the refined oil down the sink, and by the second week something has gone sideways — the dosas taste different, one bottle has gone cloudy, and the month's oil bill has doubled. The switch is not the problem. The method is.
Here is a slower version, written for a Karnataka kitchen. It starts with one bottle.
Week one: change only the oil you use most
Look at what your kitchen actually gets through. In most Old Mysuru and Bengaluru households that is groundnut oil, and in North Karnataka it is as often safflower or niger. Change that one. Leave everything else alone.
There are two reasons. First, you get the biggest share of the benefit from the oil you use every day, not from the speciality bottle you open twice a month. Second, you learn how one unrefined oil behaves before you have four of them open at once — and open bottles are the thing that goes wrong, not sealed ones.
A 500 ml bottle of cold pressed groundnut oil is ₹220. That is a small enough bet to find out whether your family likes the taste before you commit to five litres.
What week one will look like
Three things usually surprise people, and all three are normal.
The smell is stronger. Refined oil is deodorised on purpose — that is a processing step, not an absence of smell. Cold pressed groundnut oil smells of groundnut. Sesame smells of sesame, loudly. If you have only cooked with refined oil, the first oggarane will announce itself.
There is sediment. A little cloudy settling at the bottom of the bottle is seed, not a fault. We have written about why our oil looks darker, smells stronger and leaves sediment if you want the longer version.
Your dishes taste slightly different. This is the part worth paying attention to. Some dishes are better for it; some are not. Rice baths and tempering tend to gain. A delicate kheer may not.
Week two: match the oil to the job, not the other way round
By the second week you will have a sense of where the stronger flavour helps. That is the moment to add a second oil rather than a third and fourth.
The usual second bottle is a lighter one for the cooking where you do not want the oil to speak — cold pressed sunflower oil at ₹420 a litre, or coconut oil at ₹520 if your cooking leans coastal. If you temper a lot, a 500 ml of sesame oil (ellenne) at ₹310 goes further than you expect, because you use it in spoonfuls. Our guide to which oil to use for the oggarane, and how hot covers that in detail.
The full range, with what each one is actually for, sits on the cold pressed oils page.
What not to switch in the first month
Deep frying. Not because cold pressed oil cannot handle it — groundnut oil is the traditional frying oil here for good reason — but because frying burns through oil fast, and doing it in month one triples your bill before you have decided whether you are staying. Fry in what you have, finish the bottle, and move frying across once the everyday cooking has settled.
The same goes for buying a 15 L tin on day three. It is the cheapest way to buy, eventually. It is a poor way to start.
Buying the right size for a first month
Per litre, the bigger packs are cheaper: groundnut oil is ₹360 for one litre and ₹1,750 for five, which works out to ₹350 a litre. The saving is real but modest, and it only counts if you finish the oil while it is still good.
That is the trade-off nobody mentions. We press in small batches and ask you to finish an opened container within three to six months — the reasoning is in our note on small-batch pressing. A two-person household that buys five litres to save ₹50 often ends up with oil past its best. Buy the size you will actually finish.
Storage, which is where most first months go wrong
Keep the bottle out of the window light and away from the stove. Heat and daylight are what turn an unrefined oil, not time on its own. A cupboard shelf is enough; no refrigeration needed. Coconut oil will go solid as Karnataka cools towards December, and that is simply what coconut oil does below about 24°C.
What the first month costs
A realistic starter for a family of three or four: one litre of groundnut oil at ₹360 and a 500 ml of sesame at ₹310 — ₹670, plus delivery. Free delivery takes 7–14 days, standard is ₹49 at 3–7 days, express ₹99 at 1–3 days. We pack orders in two to three business days, and all orders are prepaid at checkout.
If you are in Bengaluru, the Bengaluru delivery page has the local detail. We deliver to every district in Karnataka and ship across India.
Questions people ask in the first month
Do I have to throw away my refined oil?
No. Finish it. Running the two side by side for a few weeks is also the easiest way to tell the difference honestly, in your own cooking.
Why does my bottle look different from the last one?
Colour and smell shift a little between batches because the seed does. Groundnut pressed after one harvest is not identical to the next. Refined oil is uniform because it has been standardised; ours has not.
Should I start with the 5 L steel can?
Only if you already know you will use it. The steel can keeps light out better than a plastic container, which matters for a large volume, but it is a second-month decision.
Can I use the same oil for cooking and for hair?
Our cooking oils are pressed as food. Castor oil (haralenne) is the one we sell for hair and skin rather than the kitchen.
How do I know what I received is genuinely cold pressed?
Our FSSAI licence number, 1122632300006, is on every label and can be checked on the FoSCoS portal. The smell, the colour and the sediment are the other everyday signs.
