Brown butter and ghee both start as butter heated until its water boils off and its milk solids brown. Brown butter keeps those toasted solids in the fat; ghee has them strained out, leaving almost pure, almost water-free milk fat that is made to keep. In other words, ghee goes through a brown-butter stage on its way to the jar.
At a glance
- Both begin as butter cooked until its water boils off and its milk solids brown; brown butter keeps the toasted solids, ghee strains them off.
- FSSAI allows table butter up to 16 per cent moisture and 2 per cent milk solids-not-fat; ghee must be at least 99.5 per cent milk fat with at most 0.5 per cent moisture, and no standard defines brown butter.
- Brown butter comes off the heat when it turns caramel-coloured and smells nutty; ghee cooks on until the bubbling stops, usually at 115 to 120 °C, and is then filtered.
- Ghee keeps because it has almost no water and no milk solids; no published keeping figure exists for brown butter, so make it fresh.
- Use brown butter where its flecks and nutty taste are the point; use ghee for Indian cooking, frying, sweets and anything you store between uses.
What is the difference between brown butter and ghee?
The difference is the milk solids. Both are made by cooking butter until its water evaporates and its milk solids turn brown. Brown butter is used straight from the pan with the browned solids still in it. Ghee is filtered to remove them, so it is almost pure milk fat with almost no water.
Butter is not pure fat. India's food regulator, FSSAI, defines butter as an emulsion of the water-in-oil type and allows table butter as little as 80 per cent milk fat, up to 16 per cent moisture and up to 2 per cent milk solids-not-fat. Those solids include milk protein and milk sugar (lactose).
For ghee, FSSAI's standard for milk fat products describes processes that result in "almost total removal of water and milk solids-not-fat", with ghee allowed at most 0.5 per cent moisture and required to be at least 99.5 per cent milk fat. FSSAI's dairy standards do not define brown butter at all. It is a cooking technique, not a product category.
| Brown butter | Ghee | |
|---|---|---|
| Starting point | Butter | Butter (or cream) |
| Process | Heated until it foams, the solids settle and brown, and it smells nutty; taken off the heat | Heated until bubbling stops and the solids brown, usually at 115–120 °C; then screened and filtered |
| Water | Evaporates during browning; no standard sets a limit | At most 0.5 per cent (FSSAI) |
| Milk solids | Left in; NC State's method has no straining step | Filtered off as "ghee residue" |
| Keeping | No published shelf-life figure found | Microbiologically stable; spoils mainly by fat oxidation |
| Typical uses | On roasted oysters and cauliflower, in pecan pie and cookies | Sweetmeats, cooking and frying, baking |
Ghee's water limit is FSSAI's; its other rows come from a 2023 National Dairy Research Institute review. The brown butter rows come from NC State and Iowa State extension services.
What happens to butter as it browns?
First the butter melts and foams, and its water evaporates. The milk proteins and milk sugar left behind then react in the hot fat. These browning reactions, chiefly the Maillard reaction and caramelisation, turn the milk solids dark brown and produce the cooked flavour that both brown butter and ghee are made for.
The National Dairy Research Institute review describes this chemistry for ghee. Heat breaks down lactose, fat, proteins and amino acids, and the interaction among these heat-altered substances produces the characteristic flavour. Lactose, the review says, contributes either by taking part in the Maillard reaction or by breaking down on its own through caramelisation. The dark brown particles at the bottom of the pan, it notes, appear because of these reactions acting on the milk solids-not-fat.
NC State Extension describes the cook's view of brown butter: the milk solids separate from the butterfat, sink to the bottom of the pan and turn it brown, and the butter takes on "a deeper, nuttier flavor than regular melted butter".
Is ghee just brown butter with the solids strained out?
Very nearly. Ghee goes through the same browning stage, and then the browned solids are filtered off. The cues differ slightly. Ghee makers cook until the effervescence stops and the particles have browned. Brown butter recipes go by colour and smell, and take the pan off the heat once the butter is caramel-coloured and nutty.
The dairy science review sets out the end point used in ghee making. Heating stops when the effervescence has gone, only finer air bubbles remain, and the curd particles have browned, usually at 115–120 °C. The ghee is then screened, and once it has cooled to 60 °C it is filtered to remove the ghee residue.
A laboratory comparison from India's National Dairy Development Board hints at what heat clarification adds. Researchers made traditional desi ghee from fermented cream by heat clarification, and butter oil from fresh butter by melting and centrifuging it. They detected up to 36 volatile compounds in the desi ghee and only 16 in the butter oil. Maltol and 5-hydroxymethylfurfural turned up only in the desi ghee. The samples differed in raw material as well as method, and were few, so the study cannot say which step added the compounds or how any jar will taste. Our article on whether ghee is the same as clarified butter covers that browning in more detail.
How do you tell each stage in the pan?
Watch the pan closely. The butter melts and then foams as it heats. Solids settle on the base of the pan and start to colour. Brown butter is done when it turns caramel-coloured and smells nutty. Ghee is done when the bubbling has stopped and the solids are brown, and it is then strained.
- Melting. The butter turns liquid. Nothing has browned yet, and the water is still in it.
- Foaming. The water starts to boil off. NC State notes that after a few minutes the butter begins to foam and solid particles begin to settle at the bottom of the pan.
- Settling. The solid particles collect on the base of the pan, still pale at first.
- Browning: brown butter is ready. The solids colour and the butter turns a caramel colour with a nutty aroma. NC State's advice is to take the pan off the heat at this point and watch carefully to avoid burning.
- Quiet: ghee's end point. For ghee, cooking continues until the effervescence stops, only fine bubbles remain and the particles have browned, the end point the dairy review gives.
- Straining: ghee is finished. The fat is screened and filtered off the brown residue, which is set aside.
Stages 4 and 5 sit close together, and NC State's warning about burning applies to both.
Which keeps longer, brown butter or ghee?
Ghee is the one made to keep: it has almost no water and no milk solids, while brown butter keeps its solids. The dairy science review calls ghee microbiologically stable because of its very low moisture, under 0.5 per cent, and notes that the absence of milk solids-not-fat does not support bacterial growth. It spoils mainly by fat oxidation.
The review is clear that ghee does spoil eventually: its unsaturated free fatty acids make it susceptible to oxidation, which changes its taste and nutritive value over time. Our page on the bilona process describes the curd-churned method step by step.
For brown butter, we found no study of how long it keeps, so we give no figure. Of the two reasons the review gives for ghee's stability, brown butter meets the first only as well as the cook managed, with no standard to check against, and the second not at all. Make it for the dish you are cooking.
Do brown butter and ghee taste the same?
No, though both taste cooked rather than fresh, because both have been browned. Brown butter, in NC State's words, has a deeper, nuttier flavour than melted butter, and it carries its browned solids as visible flecks. Ghee has no solids left in it; FSSAI's standard describes its "especially developed flavour" from its method of manufacture.
How strong ghee's flavour is depends on how it was made. The NDDB comparison above detected more volatile compounds in desi ghee made from fermented cream (up to 36) than in three industrial ghees (22 to 29) or butter oil (16).
When should you use brown butter, and when ghee?
Use brown butter when you want its nutty flavour and flecks to be part of the dish: shellfish and roasted vegetables, a pie filling, cookies. Use ghee when you need an everyday fat for Indian cooking, frying and sweets, or one you can keep between uses rather than make fresh each time.
- Brown butter. NC State's recipes use it on roasted oysters, in a pecan pie and over roasted cauliflower with capers. Iowa State University Extension notes that browning butter evaporates its water and gives a very dense but flavour-rich cookie.
- Ghee. The dairy science review lists its uses as the preparation of sweetmeats and the cooking and frying of different products. In baking it behaves like a melted fat with almost no water; our guide to baking with ghee gives the weights for swapping it in for butter.
- Swapping one for the other. Ghee in place of brown butter gives you fat and some cooked flavour, but not the toasted solids. Brown butter in place of ghee brings solids that have already browned into a pan that may get hotter still, and we know of no tested guidance on how they behave there.
Brown butter is made on the day. Ghee, such as Himdhara's, curd-churned and clarified slowly over a wood fire, is the browned fat with the solids taken out, made to keep.
The short version
Brown butter and ghee are made the same way up to a point: butter is cooked until its water boils off and its milk solids brown through the Maillard reaction and caramelisation. Brown butter is taken off the heat at the nutty stage and used with its browned solids. Ghee is cooked until the bubbling stops, then filtered, leaving milk fat with at most 0.5 per cent moisture under FSSAI's standard. Ghee's low water and lack of milk solids are why it keeps; we found no keeping figure for brown butter, so make it fresh.
