Mastering the chemistry of cacao can be a fickle business. If your last batch didn't quite have that "boutique" finish, don't worry—most chocolate mishaps can be traced back to one of these five common culprits.
1. The Mystery of the White Streaks (Fat Bloom)
The Symptom: Your chocolate has developed white or greyish streaks or spots on the surface.
The Cause: This is "Fat Bloom." It happens when the cocoa butter crystals haven't been properly stabilised during tempering, causing the fat to rise to the surface.
The Fix: Your chocolate is still perfectly safe to eat. However, to prevent this in the future, ensure you are hitting your precise temperatures during the cooling phase. If the chocolate stays too warm for too long, the fat will separate.
2. The "Grainy" Texture (Sugar Bloom)
The Symptom: The surface looks dull and feels gritty or sandy on the tongue.
The Cause: "Sugar Bloom." This is usually caused by moisture. If chocolate is stored in a damp fridge or if condensation forms on the bar, the sugar dissolves and recrystallises into large, crunchy grains.
The Fix: Always store your finished bars in a cool, dry place (15°C–18°C)—never the fridge unless it is airtight. Also, ensure your sweetener is as fine as possible (blitz it into a powder) before adding it to your Cacao Liquor.
3. The Sudden Clumping (Seizing)
The Symptom: One minute your chocolate is silky and melting; the next, it turns into a thick, dry, unworkable paste.
The Cause: Water. Even a single drop of steam or water from your bain-marie will cause the sugar and cocoa solids to stick together.
The Fix: If it seizes, you unfortunately cannot use it for bars anymore. However, don't throw it away — stir in a little warm cream or coconut milk to turn it into a delicious chocolate ganache or sauce.
4. No "Snap" (Improper Tempering)
The Symptom: The chocolate bends or crumbles rather than snapping cleanly when broken. It might also melt instantly when you touch it.
The Cause: The chocolate didn't reach the correct "beta" crystalline state. This usually means it was poured into the moulds while it was still too warm.
The Fix: Check your thermometer calibration. For dark chocolate made with our Cacao Butter, you need that final "working" temperature to be exactly 31°C–32°C.
5. Bubbles and Holes
The Symptom: The back of your bar is covered in small pits or air bubbles.
The Cause: Air trapped during the pouring process.
The Fix: Tap, tap, tap. Once you pour the chocolate into the mould, lift it an inch off the counter and drop it firmly several times. This vibrates the air bubbles to the surface where they can pop.
Pro Tip: Keep a notebook. Note down the humidity of your kitchen, the exact brand of sweetener used, and your tempering temperatures. This "lab log" is how the best chocolatiers achieve consistency every single time.
