You’re happily melting chocolate and suddenly it goes from smooth and glossy to thick, grainy, clumpy nonsense. Congratulations. Your chocolate has seized.

Why Does Chocolate Seize?

Chocolate does not love moisture. Even a small amount of water or steam can cause the sugar and cocoa particles to clump together, turning beautifully melted chocolate into a thick, grainy mess. Too much heat can cause trouble, too.

Can You Save It?

Usually, yes—as long as the chocolate isn’t burned.

If your chocolate has seized, try adding a small amount of fat and stirring until it begins to loosen and smooth out. In my video, I used coconut oil, but another fat can work too depending on what you’re making.

Start small. You can always add a little more, but you can’t take it back out.

There Is One Catch

Once you rescue chocolate by adding fat, you’ve changed the consistency. It can still be useful in plenty of recipes, but it may not behave exactly like the melted chocolate you started with—especially if you needed it to set up hard for dipping or coating.

When to Admit Defeat

If the chocolate smells burned or tastes scorched, adding coconut oil isn’t going to perform a miracle. Sometimes the rescue technique is throwing it away and starting over.

Keep It From Happening Next Time

If you’re using the microwave, heat in short intervals and stir between each one.

Make sure your bowl and utensils are completely dry.

Keep steam and stray drops of water away from the chocolate.

Use gentle heat rather than trying to rush the melting process.
