Chocolates & Pastries — Theobroma Cacao, Cocoa Production, Types, Tempering & Non-Laminated Pastries

By Tourism369 · Food Production Operations & Management · UGC NET Paper 2

Chocolate’s botanical name means “Food for Gods.” Its melting point is slightly below human body temperature — that’s why it melts in the mouth. Chocolate eaten in moderation can lower blood pressure. Here is the complete guide to chocolate and non-laminated pastries.

🍫 What Is Chocolate?

Chocolate is made from the bean of Theobroma Cacao — meaning “Food for Gods”. Native to lowland tropical South America. Earliest documented use: ~1100 BC in Central America and Mexico. All Mesoamerican peoples made chocolate beverages — including the Maya and the Aztec. Cocoa seeds have intense bitter taste — must be fermented to develop flavour. After fermentation, roasting and grinding → chocolate.

Key physiological facts: Contains alkaloids theobromine and phenethylamine. Chocolate’s melting point is slightly below human body temperature → melts in mouth. Scientists claim moderate consumption lowers blood pressure. Theobromine renders chocolate toxic to some animals. Theobromine is a mild stimulant in the methylxanthine family (related to caffeine).

🌱 From Cocoa Bean to Chocolate — Production Steps
1
Harvesting: Cocoa pods harvested from Theobroma Cacao trees
2
Fermentation: Seeds fermented to develop flavour — removes bitterness. Essential step.
3
Drying: Fermented beans dried to reduce moisture content
4
Roasting: Develops chocolate flavour and colour. Roasting temperature and time = critical.
5
Winnowing: Shells removed from roasted beans to obtain cocoa nibs
6
Grinding (Cocoa Mass/Liquor): Nibs ground into cocoa mass (cocoa liquor). Contains cocoa solids + cocoa butter.
7
Pressing: Cocoa mass pressed → separates cocoa butter + cocoa powder (cake)
8
Conching: Chocolate mixture mixed and aerated for hours to days → smooth texture, developed flavour
9
Tempering: Controlled heating and cooling of chocolate → stable crystalline structure → glossy finish + clean snap
10
Couverture: High-quality chocolate with minimum 32% cocoa butter. Used by professional chocolatiers for coating and moulding.
🍫 Types of Chocolate
Dark Chocolate (Plain / Bitter)
High cocoa content (35–100%). No milk solids. Strong, intense flavour. Highest theobromine content. Used in ganaches, truffles, mousses, sauces.
Milk Chocolate
Contains cocoa mass + cocoa butter + milk solids + sugar. Milder, sweeter, creamier. Lower cocoa content than dark. Most widely consumed form.
White Chocolate
Contains cocoa butter + milk solids + sugar — NO cocoa solids/mass. Ivory or cream coloured. Technically not “chocolate” since it lacks cocoa solids. Delicate, sweet, milky flavour.
Couverture Chocolate
Professional quality. Minimum 32% cocoa butter content. High fluidity when melted — ideal for coating, moulding, dipping. Must be tempered before use. Available in dark, milk, and white varieties.
Cocoa Powder
Cocoa mass after cocoa butter is pressed out. Two types: Natural (acidic) and Dutch-processed (treated with alkali → darker colour, milder flavour).
🌡️ Tempering Chocolate

Tempering = controlled process of melting and cooling chocolate to achieve stable Form V crystal structure. Properly tempered chocolate: glossy appearance + clean snap + melts smoothly + good shelf life. Un-tempered chocolate develops “bloom” (whitish surface).

Tempering Steps (Tabling Method)
1. Melt chocolate to 45–50°C (remove all crystals)
2. Pour 2/3 onto marble slab, work with palette knife until 27°C (seed crystals form)
3. Return to remaining 1/3 warm chocolate
4. Warm gently to working temperature: Dark = 31–32°C · Milk = 29–30°C · White = 28–29°C
🥐 Non-Laminated Pastries
Short Crust Pastry (Rub-in Method)
Classic pastry for pies and tarts. Weak flour + fat + small amount of cold water. Fat rubbed into flour until resembles breadcrumbs. Water added to bind. Resting (relaxing gluten) before baking essential. Two types: Plain short crust (savory) and Sweet short crust (sweet/dessert tarts).
Key principle: KEEP COLD at every stage. Handle minimally.
Choux Pastry (Hot Water Crust)
Unique pastry — made by cooking flour in boiling water + butter, then beating in eggs. Creates hollow puffs when baked (steam from high egg moisture content). Very light and airy. Used for: Éclairs, Profiteroles (Cream Puffs), Paris-Brest, Gougères (savory).
Key: eggs beaten in gradually when dough cools slightly (must not scramble). High oven temp initially to create steam → puffing. Then lower temp to dry out.
Hot Water Crust
Made with boiling water and lard. Unlike other pastries — water is HOT. Strong and robust structure holds its shape when raised (hand-raised pies). Traditional for pork pies in Britain.
Sweet Short / Sablé Pastry
Enriched with sugar and egg yolks. Crumbly, biscuit-like texture. Used for high-quality tartlet bases and petit fours.
