Learn how to melt single-origin chocolate bars without seizing, with a simple double-boiler method, a seizing fix, and tips for 70% chocolate in brownies and baking.
Quick answer
Melt single-origin chocolate gently over a double boiler: chop the bar evenly, keep the bowl above—not touching—simmering water, and stir slowly with a dry spatula. If the chocolate turns grainy or stiff, stir in 1 teaspoon of warm water or neutral oil per 2 ounces to bring it back. For 70% bars, low, even heat and zero water contact are the two rules that matter most.
Prep the bar before any heat
Single-origin bars vary in thickness, cocoa solids, and added cocoa butter, so uniform pieces melt at the same rate. Chop the bar into pieces about the size of a chocolate chip, or pulse briefly in a food processor. If you are melting chocolate for brownies, chop the full amount first and set aside what you will fold in later so you are not stopping mid-recipe.
Set up a dry, stable double boiler
A metal or glass bowl that sits snugly over a saucepan without touching the water gives you the most control. Bring 1 to 2 inches of water to a bare simmer, then turn off the heat or keep it at the lowest setting. Any steam that condenses into the bowl can cause seizing, so keep the bowl dry and the heat indirect.
Stir slowly and watch the last lumps
Stir with a dry silicone spatula in slow circles, scraping the sides and bottom. The chocolate will look mostly melted before the last small lumps disappear; residual heat usually finishes those in 30 to 60 seconds off the heat. Over-stirring or aggressive whisking can introduce air and make the texture grainy.
Troubleshoot seizing and thickening
If the chocolate tightens into a dull, grainy paste, it has seized. A chocolate seizing fix works best when you add liquid gradually: stir in warm water or neutral oil 1 teaspoon at a time per 2 ounces of chocolate until smooth. Do not add cold liquid, and do not keep heating a seized bowl—heat drives out moisture and makes it worse.
Keep 70% chocolate workable for baking
Working with 70% chocolate bars means less sugar and more cocoa solids, so they thicken faster as they cool. If you are melting chocolate for brownies, keep the bowl over warm water while you combine other ingredients, or return it to the double boiler for 10 to 15 seconds at a time. For tempering chocolate at home, hold dark chocolate between 88°F and 91°F after melting, then test a small spoonful on parchment to see if it sets glossy.
Step-by-step melting process
- Chop the bar evenly: Cut or pulse the chocolate into chip-sized pieces so every piece melts at the same time. Checkpoint: no piece should be larger than a chocolate chip.
- Heat water to a bare simmer: Bring 1 to 2 inches of water to a simmer, then turn off the heat or set it to the lowest setting. Mistake to avoid: boiling water creates steam that can drip into the chocolate.
- Set a dry bowl over the pan: Use a metal or glass bowl that rests above the water without touching it, and make sure it is completely dry. Checkpoint: the bowl bottom should stay clear of the water.
- Stir slowly with a dry spatula: Stir in slow circles, scraping the sides and bottom, until most of the chocolate is melted. Mistake to avoid: whisking fast adds air and can make the texture grainy.
- Finish off the heat: Remove the bowl and stir for 30 to 60 seconds; residual heat will melt the last small lumps. Checkpoint: the chocolate should be smooth and glossy, not hot.
- Fix seizing with warm liquid: If the chocolate turns grainy or stiff, stir in 1 teaspoon of warm water or neutral oil per 2 ounces until smooth. Mistake to avoid: adding cold liquid or more heat, which makes seizing worse.
- Hold 70% chocolate warm for baking: For brownies and other batters, keep the bowl over warm water or reheat in 10 to 15 second bursts. Checkpoint: for tempering at home, dark chocolate should read 88°F to 91°F before you test a spoonful on parchment.
