Tempering chocolate creates a smooth, shiny finish and a satisfying snap. Many home bakers avoid it, thinking it requires fancy equipment. You can temper chocolate perfectly in a microwave. This method is fast, simple, and reliable. Follow these steps for professional results every time.
Why Temper Chocolate?
Tempered chocolate sets with a crisp texture and glossy appearance. Untempered chocolate looks dull and melts too easily in your hand. Tempering aligns the cocoa butter crystals in the chocolate. This process stabilizes the chocolate for molding, dipping, or coating.
Cocoa butter has six crystal forms. The best one, Form V, gives shine and snap. Tempering melts out unstable crystals, then encourages Form V to form. Microwave tempering controls heat precisely. It avoids the guesswork of double boilers or marble slabs.
You can temper dark, milk, or white chocolate this way. Results rival those from chocolatiers. Use tempered chocolate for truffles, bars, or decorations.
Ingredients and Tools You Need
Start with high-quality chocolate. Choose couverture if possible, but good eating chocolate works too. Avoid chocolate chips; they contain stabilizers that resist tempering.
- 12 ounces (340g) chocolate, chopped into even pieces
- Microwave-safe bowl, preferably glass
- Rubber spatula
- Digital thermometer (instant-read works best)
- Clean, dry workspace
Chop chocolate finely for even melting. Uniform pieces melt at the same rate. Wipe tools dry. Any moisture causes seizing.
Step-by-Step Guide: Tempering in the Microwave
Microwave tempering uses short bursts to prevent overheating. Patience is key. Rushing leads to thick, grainy chocolate.
Step 1: Chop the Chocolate
Break 12 ounces of chocolate into small, uniform pieces. Place them in a microwave-safe bowl. Use at least 8-10 ounces for best results; smaller amounts overheat easily.
Step 2: Melt in Bursts
Microwave on high for 15 seconds. Stir thoroughly with a spatula. Repeat: 15 seconds on, stir, until two-thirds melted. Most chocolate should be liquid, with some solid bits remaining.
For dark chocolate, aim for 105-115°F (40-46°C). Milk and white chocolate melt at 100-110°F (38-43°C). Check temperature after each burst.
Step 3: Seed with Solid Chocolate
Add 2-3 ounces of finely chopped unmelted chocolate to the bowl. This is the seeding method. Stir gently until it melts into the warm chocolate. The cool solids lower the temperature.
Continue stirring. All chocolate should melt smoothly. If lumps remain, microwave for 5 seconds and stir again.
Step 4: Cool to Tempering Temperature
Target working temperature: 88-90°F (31-32°C) for dark chocolate. Milk and white: 86-88°F (30-31°C). Place bowl over another bowl of cool water if needed. Stir constantly.
Test readiness with a small dab on parchment paper. It should set shiny and firm within 3-5 minutes at room temperature (around 68-72°F or 20-22°C).
Step 5: Use Immediately
Work quickly. Tempered chocolate stays in temper for 20-30 minutes. Enrobe candies, mold bars, or pipe decorations. Re-temper if it thickens by gently warming to 90°F (32°C) while stirring.
Tips for Perfect Microwave Tempering
- Microwaves vary in power. Start with shorter bursts if yours runs hot. 1000-watt models work best; adjust for lower power.
- Use a thermometer always. Eyeballing fails. Glass bowls retain less heat than plastic.
- Clean everything first. Chocolate hates water. Humidity above 60% can cause issues; use a dehumidifier if needed.
- Practice with small batches. Tempering improves with experience.
- Common mistakes: Overheating past 120°F (49°C) destroys crystals. Uneven chopping causes hot spots. Stirring too vigorously introduces air bubbles.
Troubleshooting Common Problems
- Chocolate seized? It turned grainy and thick. Caused by water. Discard and start over.
- Too thick? Likely out of temper. Re-melt and re-temper.
- Dull finish? Not cooled properly. Check room temperature and test dab.
- White streaks? Blooming from temperature swings. Not harmful, but remake for best look.
- Won’t set? Too warm or high humidity. Cool further or dry the air.
- Store leftovers? Tempered chocolate doesn’t keep well. Melt and re-temper next time.
Variations for Different Chocolates
Dark Chocolate
Melt to 115°F (46°C), cool to 90°F (32°C). Snaps beautifully.
Milk Chocolate
Sensitive to heat. Melt to 110°F (43°C), temper at 88°F (31°C). Stir gently.
White Chocolate
Melt to 105°F (40°C), work at 86°F (30°C). No cocoa solids, so fragile.
Colored Cocoa Butter
Follow white chocolate temps. Great for decorations.
Storage and Re-Tempering
Untempered chocolate stores for months. Tempered sets fast, so use soon. Room temperature is best: 60-70°F (15-21°C). Avoid fridge; condensation ruins shine.
To re-temper scraps: Gently melt to 90°F (32°C), seed, and cool again.
Recipes to Try with Tempered Chocolate
- Easy Truffles: Dip ganache balls in tempered chocolate. Roll in cocoa or nuts.
- Chocolate Bars: Pour into molds with nuts or sea salt. Tap to release bubbles.
- Dipped Strawberries: Rinse, dry thoroughly, then dip. Let set on parchment.
- Bark: Spread on sheet, top with pretzels and sprinkles. Break once set.

Frequently Asked Questions (FAQs)
-
Can I temper chocolate without a thermometer?
Not recommended. Temperatures must be precise for success. A cheap digital thermometer pays off quickly.
-
What if my microwave is too powerful?
Use 10-second bursts instead of 15. Or reduce power to 50-70% if adjustable.
-
Why does my tempered chocolate get streaky?
Often fat bloom from temperature changes. Ensure steady room temp and quick use.
-
Can I temper compound chocolate or melts?
No. They lack real cocoa butter. Skip tempering; they set without it.
-
How long does tempered chocolate stay usable?
20-45 minutes, depending on room temp. Work in small batches for larger projects.
