How to Temper Chocolate

Updated August 2026 · Baking Resources

Tempering is controlled crystallization. You're steering the cocoa butter in melted chocolate into one specific crystal form out of six possible ones, and that single form is what gives you snap, shine, a clean release from the mold, and a chocolate that doesn't melt the second you touch it.

You do it with temperature. Melt the chocolate fully, cool it while stirring so the right crystals form and the wrong ones don't survive, then bring it back up a few degrees to a working temperature and use it. Miss the window and you get a dull, soft, streaky result.

One thing to be clear about first: melting and tempering are two different jobs. Melting comes first, and our guide on how to melt chocolate covers the double boiler, microwave and warm oven methods along with the seizing rules. This page picks up after the chocolate is liquid and takes it through the crystal work.

What tempering actually does

Cocoa butter is stubborn stuff. It can solidify into six different crystal structures, labeled Form I through Form VI, and they are not equally good. Only one of them, Form V, makes chocolate that behaves.

Form V melts at about 94°F. Your body is 98.6°F. That's the whole magic trick: tempered chocolate is solid at room temperature and on your fingers, then melts on your tongue.

When you melt chocolate you destroy every crystal in it. If you just let it cool on its own, all six forms compete and the unstable ones, which set faster, win. Tempering is the process of stacking the deck so Form V is the only seed available.

What untempered chocolate looks like

You'll recognize it immediately once you know the signs.

• Dull, matte surface instead of a mirror finish.
• No snap. It bends or crumbles rather than breaking with a clean crack.
• Soft at room temperature, and it smears on your fingers.
• Streaks and swirls, pale marbling across the surface.
• A gray or white film, which is bloom.
• Slow setting. Properly tempered chocolate sets in 3 to 5 minutes at 65 to 70°F. Untempered can take 20 minutes or never fully firm up.
• It sticks in the mold instead of releasing with a tap.

What bloom actually is

Bloom is not mold, and it's not spoilage. It's perfectly safe to eat. There are two kinds and they come from different failures.

Fat bloom is cocoa butter that has migrated to the surface and recrystallized there, usually into Form VI. It looks like a soft gray haze or pale streaks, and it feels slightly waxy. It comes from bad tempering, or from warm storage that partially melted the chocolate and let it reset on its own. This is the one that tells you your temper failed.

Sugar bloom is different. Moisture lands on the surface, dissolves some sugar, then evaporates and leaves the sugar behind as gritty crystals. It feels sandy, not waxy. It comes from condensation, usually from moving chocolate straight from the fridge into a warm room.

Both are fixable in the sense that you can melt the chocolate and re-temper it. Neither can be polished off.

Chocolate tempering temperatures by type

This is the part that matters most, and the numbers are not the same for every chocolate. Milk and white chocolate contain milk solids and more sugar, which dilute the cocoa butter and lower every point on the curve.

Three rules hide in that table.

1. Never exceed the melt ceiling. Past about 120°F dark chocolate scorches, and milk and white scorch even lower because milk solids burn easily.
2. The cool step is not optional. Dropping to the low 80s is what lets Form V crystals seed while the unstable forms are still liquid enough to be stirred out.
3. The working temperature is a narrow band. Two degrees too warm and you melt out your Form V crystals and lose temper. Two degrees too cool and the chocolate thickens and sets in the bowl.

A digital instant-read thermometer that reads to a tenth of a degree is genuinely required here. A candy thermometer that only marks every 10 degrees can't see the window you're aiming for.

How to temper chocolate with the seeding method, step by step

Seeding is the most reliable home method by a wide margin. You melt most of your chocolate, then stir in solid, already tempered chocolate. The solid pieces carry Form V crystals with them and teach the melted chocolate what to do.

You'll need: a digital thermometer, a dry heatproof bowl, a flexible spatula, and chocolate that's already in temper. Any decent store-bought bar straight off the shelf is tempered. Callets or wafers work best because they melt evenly.

Step 1. Divide. Weigh your chocolate and set aside 25 to 30 percent as your seed. For 400 g of chocolate, melt 300 g and keep 100 g back, chopped fine.

Step 2. Melt the larger portion. Take dark to 115 to 120°F, milk to 110 to 115°F, white to 105 to 110°F. Stir the whole time. Full detail on the melting methods is in our how to melt chocolate guide.

Step 3. Take it off the heat completely. Dry the bottom of the bowl if it was over water. A drop of water at this stage seizes the batch.

Step 4. Add the seed in two or three additions. Stir in about half, wait until it's fully dissolved, then add more. Stir slowly and steadily, scraping the sides so nothing sets on the cool glass.

Step 5. Cool to the target. Keep stirring until the thermometer reads 80 to 82°F for dark, 79 to 81°F for milk, 78 to 80°F for white. If unmelted seed remains, lift it out with a fork so it can't sit as a lump.

Step 6. Warm back up gently. Return to the working temperature: 88 to 90°F dark, 86 to 88°F milk, 84 to 86°F white. Five seconds at a time in the microwave at low power, or ten seconds over warm water, stirring between. This step is where most people blow it, so go slower than feels reasonable.

Step 7. Test. Smear a little on parchment and watch it. Details below.

Step 8. Use it, and keep it in the working range while you do.

Worked example: 400 g of 60% dark chocolate

Weigh out 400 g. Chop and set aside 100 g as seed, which is 25 percent.

Melt the other 300 g in the microwave at 50 percent power in 20 second bursts, stirring between each, until the thermometer reads 118°F.

Off the heat, stir in 50 g of the seed. Watch it dissolve. Add the remaining 50 g. Keep stirring, and expect this to take 5 to 8 minutes in a 70°F kitchen. When the reading hits 81°F, stop cooling.

Now warm it to 89°F with three or four 5 second microwave bursts at 50 percent power, stirring after each. Test on parchment. Total time: about 20 minutes, and 350 g of that 400 g is what you'll actually get to use once the bowl and spatula take their share.

The tabling method, and why to skip it

Tabling is the professional technique. You pour two thirds of the melted chocolate onto a marble slab and work it with a scraper and offset spatula, spreading it thin and gathering it back, until it cools to the low 80s and thickens. Then you scrape it back into the remaining warm chocolate and stir to reach the working temperature.

It works beautifully, and it produces the most reliable crystal structure of any method. It also needs a cold marble slab, a bench scraper, a long offset spatula, a fair amount of practice, and about a square yard of counter that you don't mind covering in chocolate.

For home batches under a couple of pounds, seeding gets you the same result with a bowl and a thermometer. Learn tabling when you're producing chocolate in volume, not before.

The test that tells you if it worked

Dip the tip of a butter knife, an offset spatula, or a strip of parchment into the chocolate. Give it a thin coat, then set it on the counter at normal room temperature, 65 to 70°F. Don't put it in the fridge, because the fridge makes untempered chocolate look temporarily fine.

Tempered chocolate sets in 3 to 5 minutes. It looks glossy. It feels firm and dry, not tacky. Snap it and you hear a crack and see a clean, matte edge.

Untempered chocolate is still soft or sticky at 5 minutes. It looks dull or streaky. It bends instead of snapping.

If the test fails, you can fix it. Warm the whole batch back to the full melt temperature, wiping out every crystal, and start over from step 2. Chocolate can be re-tempered many times without harm as long as you never scorch it and never let water in.

Holding temper while you work

Tempered chocolate isn't done once you've tempered it. Form V keeps growing, so the chocolate thickens as you work, and it loses temper if it drifts out of range.

Keep it in the working band. 88 to 90°F for dark, 86 to 88°F for milk, 84 to 86°F for white. A heating pad on low under a folded towel works. So does a bowl set over water that's warm to the touch, around 100°F, not hot.

Stir every couple of minutes. Standing still means the edges cool and set while the center stays warm.

Watch the room. A kitchen at 65 to 70°F is ideal. Above 75°F, chocolate refuses to set properly. Below 60°F, it sets too fast and can bloom.

Things that break temper:

• Overheating past 94°F. Every Form V crystal melts out, and you're back to untempered liquid. This is the number one cause.
• Water. A drop of steam or a wet mold seizes the batch instantly.
• Cold molds or cold fillings. They shock the chocolate into unstable crystals at the contact surface, which is why one side of a bonbon comes out dull.
• Letting it sit and thicken past use. Warm it 1 or 2 degrees, stir, and carry on. Don't blast it.
• The refrigerator. Chilling to set is a shortcut that trades gloss for speed and causes condensation on the way out.

When you do not need to temper at all

Tempering only matters when the chocolate has to set hard on its own and look good doing it. That's coating, dipping, molding, bark, decorations and shavings. Fondant toppers are the other route and need no tempering at all, which how to make fondant decorations walks through.

You can skip it entirely for:

• Anything going into a batter. Brownies, cakes, cookie dough. The chocolate melts again in the oven, so crystal structure is meaningless.
• Ganache. Cream is added, the fat structure changes completely, and temper has nothing to hold onto.
• Frostings and buttercreams. Same reason. Melt it, cool it slightly, beat it in. Our guide on how to frost a cake has the consistency targets.
• Sauces, glazes and drizzles that stay soft or get refrigerated.
• Mousse, ice cream, puddings, hot chocolate.
• Truffle centers, though the outer shell does need temper if you're dipping.

That list covers most home baking. Save the thermometer for the projects where snap and shine are the point.

Frequently asked questions

Can I temper chocolate without a thermometer?

Not reliably. The whole technique is built on a working window that's about 2 degrees wide, and no one can judge that by feel. If you're determined, use the seeding method, add plenty of seed, and let the excess unmelted seed hold the temperature down, then test on parchment before you commit the batch.

Can I temper chocolate chips?

Usually not well. Most chips contain stabilizers and less cocoa butter so they hold their shape in the oven, which is the opposite of what you want in a coating. Use couverture, callets, or a good bar with a high cocoa butter content instead.

Why did my tempered chocolate turn out streaky?

Streaks mean part of the batch had Form V and part didn't, which is almost always uneven temperature. Either the warm-up step overshot 94°F in one spot, or the chocolate wasn't stirred enough while cooling. Remelt fully and redo it.

Is bloomed chocolate safe to eat?

Yes. Fat bloom and sugar bloom are both cosmetic, not spoilage. The texture suffers, but you can melt bloomed chocolate and re-temper it, or chop it into a batter where nobody will know.

How long does tempered chocolate stay good?

Months, if you store it at 60 to 68°F somewhere dry, away from light and strong smells. Keep it out of the fridge, since condensation causes sugar bloom and chocolate readily absorbs odors.

Do I need to temper white chocolate differently?

Same method, lower numbers. Melt to 105 to 110°F, cool to 78 to 80°F, work at 84 to 86°F. White chocolate has no cocoa solids to buffer the milk solids and sugar, so it scorches easily and needs a gentler hand throughout. If tempering is the step you want to skip, white chocolate vs candy melts covers what you give up.

What is the fastest way to temper a small amount?

Seeding, using a lot of seed. Melt about 60 percent of your chocolate, then stir in the remaining 40 percent all at once off the heat. The large cold addition drags the temperature into the low 80s in one move, and often lands you close to the working range with almost no reheating.

Why won't my chocolate set even though it's tempered?

Check your room first, since above 75°F nothing sets properly. If the room is fine, the coating may be too thick, or a wet or oily surface underneath is interfering. Damp fruit is the usual suspect, so dry everything thoroughly before dipping.
