About 80–82% of butter is fat; the rest is water and milk solids. The part that burns is not the fat but those milk solids, which begin to brown at a relatively low temperature. That is why butter foams in a hot pan, then browns and quickly turns bitter. The solution is to add a neutral oil or use clarified butter with the milk solids removed.
Butter is not pure fat. About 80–82% of it is milk fat; the rest is water and milk solids, meaning proteins and milk sugar. These three components behave differently when heated. Fat withstands high temperatures, water boils off, and milk solids begin to color at a relatively low temperature before browning and turning bitter. That is why what burns in the pan is not the fat itself. Butter’s heat tolerance therefore cannot be compared directly with that of pure fats.
You can follow the process in the pan step by step. Butter melts first, then foams as its water evaporates. Once the foam subsides, fat and small solid particles remain; the particles settle on the bottom of the pan and quickly take on color there. For a short time, a nutty aroma develops, which is a desired stage; but over high heat, that stage lasts only seconds, and burning follows immediately. The pan’s color also makes it easier to track this stage; the change is visible much sooner in a light-colored pan.
That is why butter is not used on its own for tasks such as frying that require high, sustained heat. A common solution is to add a neutral oil. This does not change the temperature at which the milk solids burn, but it dilutes the particles and distributes heat more evenly across the pan, significantly delaying browning. It works in practice, but it is a limited solution. So even when using the mixture, keep the heat at a medium level and stay by the pan.
The main solution is to remove the milk solids. When butter is melted and strained to remove the milk residue and water, almost pure fat remains; this product is about 99.5% fat and can withstand much higher temperatures. Because no solid remains to burn, it can be used comfortably for frying. Its flavor is also different from butter’s: richer and more caramel-like. You can make the same product at home by melting butter, letting it stand, and straining off the clear portion.
There is a third, most practical approach: use butter for flavor rather than for heat. Cook vegetables, meat, or pasta in neutral oil; after turning off the heat, add a piece of butter and let it melt over the food. This gives you the flavor of butter while completely eliminating the risk of burning. The same method is used to finish sauces. It also preserves butter’s aroma, which is lost during prolonged heating. That is why butter has two separate roles in the kitchen: one for heat and the other for flavor.

Sade yağla karıştırarak kullanıyorum, tereyağının kokusu kalıyor ama yanma olmuyor.
İyi bir orta yol. Süt kuru maddesini tamamen çıkarmak isterseniz tereyağını eritip köpüğünü ve dibe çöken tortuyu ayırmak da var; kalan berrak yağ yüksek ısıda kararmıyor.
Köpüğün kesilip rengin dönmeye başladığı an gerçekten hızlı geliyor, bir dalgınlıkta kararıyor.
