Introduction: Understanding Chocolate
Chocolate working is the art and science of manipulating chocolate for confectionery, baking, and decorative purposes. Working with chocolate requires understanding its unique properties, particularly how cocoa butter crystallizes at different temperatures. Mastering chocolate techniques allows for the creation of glossy, snappy chocolate that melts smoothly in the mouth and can be formed into beautiful decorations, shells, bonbons, and showpieces.
Core Concepts: Chocolate Fundamentals
Types of Chocolate
Type | Cocoa Solids | Cocoa Butter | Sugar | Milk Solids | Characteristics |
---|---|---|---|---|---|
Dark | 50-100% | 10-12% | 0-50% | None | Bold, complex flavor; less sweet |
Milk | 10-50% | 10-12% | 20-50% | 12-25% | Creamy, sweet, moderate chocolate flavor |
White | 0% (no cocoa solids) | 20-30% | 40-60% | 14-25% | Sweet, vanilla, buttery flavor |
Ruby | 47-48% | Similar to dark | 20-30% | 12-15% | Naturally pink, berry-like flavor |
Couverture | Varies by type | 32-39% min | Varies | Varies | High cocoa butter, professional quality |
Compound | Varies | None (replaced with vegetable fat) | Varies | Varies | No tempering needed; inferior mouthfeel |
The Crystallization Process
Chocolate contains six different types of crystals (polymorphs), but only Type V crystals produce properly tempered chocolate:
Crystal Type | Melting Point | Characteristics |
---|---|---|
I | 17°C (63°F) | Soft, crumbly texture |
II | 21°C (70°F) | Soft, crumbly texture |
III | 26°C (78°F) | Firm but poor snap and appearance |
IV | 28°C (82°F) | Firm but dull appearance |
V | 32-34°C (89-93°F) | Glossy, firm, good snap, stable |
VI | 36°C (97°F) | Hard, brittle, takes weeks to form |
Step-by-Step: Chocolate Tempering Methods
Traditional Tabletop Tempering Method
Preparation:
- Chop chocolate into small, even pieces
- Reserve 25-30% of chocolate for seeding
- Ensure all tools are completely dry (water is chocolate’s enemy)
Melting (Phase 1):
- Heat 70-75% of chocolate to:
- Dark: 55-58°C (131-136°F)
- Milk: 45-48°C (113-118°F)
- White: 40-45°C (104-113°F)
- Stir occasionally to ensure even melting
- Heat 70-75% of chocolate to:
Cooling (Phase 2):
- Add reserved chocolate (seeding method)
- Stir continuously, cooling the chocolate to:
- Dark: 28-29°C (82-84°F)
- Milk: 27-28°C (81-82°F)
- White: 26-27°C (79-81°F)
Working Temperature (Phase 3):
- Gently reheat to working temperature:
- Dark: 31-32°C (88-90°F)
- Milk: 30-31°C (86-88°F)
- White: 29-30°C (84-86°F)
- Gently reheat to working temperature:
Testing Temper:
- Dip metal knife tip or piece of parchment in chocolate
- Allow to set 3-5 minutes at room temperature
- Properly tempered chocolate will:
- Set quickly
- Be firm to touch
- Have uniform glossy appearance
- Not show streaks or spots
Seeding Method (Simplified)
- Melt 2/3 of chocolate to proper melting temperature
- Remove from heat and add 1/3 finely chopped tempered chocolate
- Stir continuously until completely melted and cooled to working temperature
- Test temper as described above
Direct Seeding Method
- Place all chopped chocolate in bowl
- Heat gently until approximately 60% is melted
- Remove from heat and stir until all chocolate is melted
- Test temper
Microwave Tempering
- Chop chocolate finely and place in microwave-safe bowl
- Microwave at 50% power in 30-second intervals, stirring between each
- Once 70% melted, stir until completely melted
- Test temper
Sous Vide Tempering
- Seal chopped chocolate in vacuum bag
- Place in water bath set to working temperature for 24-48 hours
- Chocolate will be perfectly tempered when removed
Chocolate Working Techniques
Molding Techniques
Technique | Description | Best Used For |
---|---|---|
Shell Molding | Create hollow shapes by coating molds with layers of chocolate | Bonbons, hollow figures, filled chocolates |
Solid Molding | Fill molds completely with tempered chocolate | Solid chocolate bars, decorative elements |
Double-Shell | Create two-tone or layered shells | Artistic bonbons, visual contrast |
Transfer Sheets | Place printed transfer sheets in molds before adding chocolate | Patterned/decorated chocolate surfaces |
Spinning | Rotating a filled mold to create even shell thickness | Hollow eggs, spheres |
Shell Molding Process
- Fill clean, room-temperature mold with tempered chocolate
- Tap to remove air bubbles
- Invert mold to empty excess chocolate
- Scrape flat surfaces clean
- Allow to set until edges begin to pull away from mold
- Fill with ganache/filling if desired
- Seal with additional tempered chocolate if making filled chocolates
- Allow to fully crystallize (15-30 minutes)
- Unmold by tapping gently or flexing mold
Decoration Techniques
Technique | Description | Difficulty Level |
---|---|---|
Piping | Creating designs with paper cones or piping bags | Beginner to Intermediate |
Transfer Sheets | Using acetate with cocoa butter patterns | Beginner |
Chocolate Cigarettes | Thin strips curled from acetate | Intermediate |

Creating Chocolate Decorations
Chocolate Curls:
- Spread thin layer of tempered chocolate on marble
- When almost set (still pliable), scrape with bench scraper at 45° angle
Chocolate Fans:
- Spread thin strip of chocolate on acetate
- When beginning to set, lift and fold into fan shape
- Allow to fully crystallize before moving
Transfer Sheets:
- Place transfer sheet pattern-side up
- Spread thin layer of tempered chocolate
- Allow to begin setting
- Cut desired shapes before fully hardened
- Remove acetate when completely set
Working with Ganache and Fillings
Basic Ganache Ratios
Type | Chocolate:Cream Ratio | Best For |
---|---|---|
Firm/Cutting | 2:1 to 3:1 | Bonbon fillings, truffles |
Soft/Spreading | 1:1 to 2:1 | Cake fillings, softer centers |
Whipped | 1:1 | Mousse, frosting |
Glaze | 1:2 | Pourable glaze |
Ganache Process
- Heat cream to simmer with any flavorings
- Pour over finely chopped chocolate
- Let stand 1-2 minutes
- Stir from center outward until emulsified
- Add butter or liqueurs if desired
- Cool to working consistency
Comparison: Troubleshooting Chocolate Issues
Issue | Appearance | Causes | Solutions |
---|---|---|---|
Blooming (Fat) | White/gray surface film | Poor tempering; temperature fluctuations | Re-temper completely; store at stable temperature |
Blooming (Sugar) | Rough, sandy surface | Condensation on chocolate | Control humidity; avoid refrigeration without sealing |
Seized Chocolate | Thick, grainy paste | Contact with water; overheating | For minor seizing, add neutral oil (1 tbsp per pound); severe cases require starting over |
Thick/Unworkable | Too thick to pour/dip | Overcrystallization; cooling | Gently rewarm to working temperature |
Soft/Unset | Doesn’t harden properly | Undertempered; too much fat added | Re-temper; adjust recipe if fats were added |
Spots/Streaks | Uneven appearance | Uneven crystallization; temperature shock | Ensure even cooling; maintain stable environment |
Sticking to Molds | Difficult to release | Insufficient tempering; warm molds | Properly temper; ensure molds are clean and at room temperature |
