The most common reason chocolate seizes while melting in a water bath is that a drop of water or steam gets into the bowl and combines with the cocoa solids and sugar, turning the chocolate into a gritty, solid mass. In cooking, this is called seizing. It happens when the balance between the chocolate's fat and water is disrupted.
Why does contact with water cause a problem?
Chocolate normally contains almost no water and has a high fat content, which lets it melt into a smooth, fluid texture. A small amount of water entering the bowl wets the sugar particles in the cocoa and makes them stick together. This separates them from the liquid fat phase and turns the chocolate into a thick, grainy mass. Although a small amount of water can cause a problem, deliberately adding a large amount of liquid, for example when making a sauce, prevents this separation. The issue is a small, uncontrolled amount of water getting into the chocolate.
How can you prevent chocolate from seizing?
The bowl used for a water bath should not touch the boiling water below it; it should be heated only by steam. If the bowl touches the water, the risk of overheating and steam splashing increases. Make sure the spoon and bowl are completely dry before adding the chocolate pieces. If the bowl has no lid, take care while stirring so steam rising from the pot does not condense and drip into the bowl. Choose a bowl larger than the pot below it.
Can seized chocolate be saved?
Adding small amounts of hot water or boiling cream to seized chocolate and stirring quickly can sometimes make it fluid again. The idea is not to reduce the water but to add enough liquid to reverse the separation. This does not always work, and the chocolate may no longer be pure enough to pour into a mold and let set. In that case, use it in a recipe that includes liquid, such as a sauce or ganache.
Is melting chocolate in the microwave safer?
Compared with a water bath, microwaving completely eliminates the risk of contact with steam, making it an alternative that reduces the risk of seizing. However, moisture still needs to be kept out, and the container holding the chocolate must be dry. Stop and stir at short intervals, every 15–20 seconds, to help prevent the chocolate from burning or clumping in the microwave.
White and milk chocolate have lower burning points than dark chocolate. For these varieties, shortening the microwave intervals slightly and stirring more often noticeably reduces the risk of burning. Burnt chocolate is different from seized chocolate and generally cannot be saved. It has a bitter taste and sharp smell; in that case, the best choice is to discard it and start over.
Heating the chocolate carefully and patiently helps prevent seizing and burning. Rushing and raising the heat are common triggers for both problems. Before melting, break the chocolate into pieces that are as small and uniform as possible. This helps the heat spread evenly and prevents larger pieces from melting on the outside while remaining solid inside.

Kaseyi tencereden büyük seçmediğim için kenardan buhar sızıp içine damladı, çikolata birden kum gibi taneli bir hâle geldi. Sıcak krema ekleyip kurtarmaya çalıştım, tam eskisi gibi olmasa da ganaj olarak kullanabildim.
Tam olarak beklediğimiz senaryo, kase küçük kalınca kenardan buhar kaçması çok yaygın bir hata. Sıcak kremayla kurtarmanız doğru bir hamle, bir dahakine kaseyi biraz daha büyük seçmeyi deneyebilirsiniz.
