Frequently Asked Questions

Tempering is the process of heating and cooling chocolate to specific temperatures to stabilize cocoa butter crystals. Properly tempered chocolate has a glossy finish, snaps cleanly, and doesn't bloom (develop white streaks). Without tempering, chocolate appears dull, melts too easily at room temperature, and lacks that satisfying snap.

Dark chocolate (50–70% cocoa) should be melted at 45–50°C (113–122°F), cooled to 27–28°C (80–82°F), then gently reheated to a working temperature of 31–32°C (88–90°F). Always use a reliable digital thermometer for accuracy.

Untempered or poorly tempered chocolate will develop fat bloom (whitish-gray streaks on the surface), feel soft or sticky at room temperature, lack a clean snap, and melt too quickly when handled. It may also stick to molds and be difficult to unmold cleanly.

Yes! The microwave method is excellent for small batches. Use short bursts (15–20 seconds) at medium power, stirring thoroughly between each burst. Heat only until about 75% melted, then let residual heat melt the rest. Be extremely careful not to overheat — chocolate burns easily and becomes grainy and unusable.

The seeding method involves adding already-tempered chocolate (the "seed") to melted chocolate to encourage proper crystal formation. Add about 25–30% seed chocolate by weight to your melted chocolate at around 40°C, stir continuously as it melts and cools, and the stable cocoa butter crystals from the seed will "seed" the entire batch. This is the easiest and most reliable method for home chocolatiers.

The "knife test" is the simplest method: dip the tip of a clean knife or a strip of parchment paper into the chocolate and let it sit at room temperature (18–22°C / 65–72°F). Properly tempered chocolate should set within 3–5 minutes, appear glossy, and snap cleanly. If it stays soft, streaky, or takes longer than 7 minutes, re-temper.

The main difference is the working temperature range. Dark chocolate tolerates higher temperatures (working at 31–32°C), while milk chocolate is more delicate (29–30°C), and white chocolate is the most sensitive (28–29°C) due to its high milk solids and cocoa butter content. White chocolate also scorches more easily, so gentle heating is essential.

Absolutely. Bloomed chocolate is perfectly safe to eat and can be re-tempered. Simply melt it completely to 45–50°C (which resets all cocoa butter crystals), then follow the full tempering process again. The bloom will disappear once properly tempered and cooled.

Chocolate seizes when even a tiny amount of water or steam comes into contact with it. The sugar particles absorb the moisture and clump together, creating a grainy, stiff mass. Always use completely dry bowls and utensils, and never cover hot chocolate with a lid (condensation drips). If seizing occurs, unfortunately the chocolate cannot be salvaged for tempering, but you can add warm cream to turn it into a ganache.
