Lower the heat when making ghee if you notice the milk solids are browning too quickly, the ghee is smoking, or a burnt smell is present. These signs indicate the ghee is overheating and could burn.
Making ghee involves simmering butter to separate the milk solids and water, leaving behind pure butterfat. The process requires careful monitoring to prevent burning. Here's a breakdown of the signs that indicate you should lower the heat:
Rapid Browning of Milk Solids: As the butter melts and simmers, milk solids will begin to separate and settle at the bottom of the pot. If these solids are browning very quickly, turning dark brown or black within a short period, it's a clear sign the heat is too high. The goal is to gently toast the milk solids to a golden-brown color, not burn them.
Smoking Ghee: Ghee has a relatively high smoke point, but if you see smoke rising from the pot, it means the ghee is exceeding its smoke point and is starting to burn. Immediately reduce the heat to prevent a bitter, burnt flavor.
Burnt Smell: The most obvious sign is the smell of burning. If you detect a burnt or acrid odor, it's crucial to lower the heat or even remove the pot from the heat temporarily to prevent further burning. A properly made ghee should have a nutty, pleasant aroma.
Vigorous Bubbling: While some bubbling is normal as the water evaporates, excessively vigorous bubbling can indicate that the heat is too high and the ghee is at risk of splattering and burning.
Use a heavy-bottomed pot to make ghee. This helps distribute the heat more evenly and prevents hot spots that can lead to burning. Also, stirring occasionally can help prevent the milk solids from sticking and burning to the bottom of the pot.
