Butter vs ghee and clarified butter
What clarification removes is the point: take out the water and the milk solids and two of butter’s four jobs go with them.
The short answer
Ghee substitutes well where butter was providing flavour and tenderness, and badly where it was providing water or browning. That makes it a reasonable swap in many cakes and biscuits, a poor one in laminated pastry, and a change worth thinking about anywhere a golden crust was the aim.
Where they differ
| Dimension | First | Second |
|---|---|---|
| Water | About a sixth, which becomes steam. | Removed. No steam contribution at all. |
| Milk solids | Present, and they brown by the Maillard route. | Removed after they have flavoured the fat. Less browning from the fat itself. |
| Flavour | Buttery and mild. | Nuttier and more pronounced in ghee; clarified butter is milder than either. |
| Lamination | The reference fat, and the steam is part of the mechanism. | Poor. No water, and it is often sold soft enough to be the wrong state before you start. |
| Keeping | Needs refrigeration. | Keeps at room temperature, because what spoiled has been taken out. |
| Fat per gram | Lower — the water and solids make up the rest. | Higher. A one-for-one swap by weight is a change in three variables, not one. |
