Pancyprian TS Cooking Arts: Vegetables, Legumes, Farinaceous Products and Egg Cookery

Vegetables, Legumes, Farinaceous Products and Egg Cookery tests pigments, textures and safety on the non-protein side of the plate. Expect questions on blanching and shocking, pigment behaviour with acid and alkali, legume preparation and yields, pasta and rice cookery, and the coagulation of egg proteins.

Vegetables

Chlorophyll turns olive-grey in acid; cook green vegetables uncovered and fast, then shock in ice water.
Anthocyanins in red cabbage and beetroot stay red with acid and turn blue-green with alkali.
Carotenoids are relatively stable; flavones in cauliflower and onion stay white with acid and yellow with alkali.
Use minimal water, salt the cooking water, cook al dente and avoid crowding.

Legumes

Soak 8–12 hours and discard the water; lentils and split peas need no soaking.
Kidney beans must boil hard for at least 10 minutes to destroy phytohaemagglutinin.
Add acid such as tomato late, or skins toughen.
Yields: chickpeas about ×2.2–2.4, lentils about ×2.5.

Farinaceous products

Long-grain rice at 1 : 1.5–1.8 rice to water by volume; risotto 1 : 3 with stock added gradually.
Pasta: 1 L water per 100 g and 10 g salt per litre; drain al dente and reserve cooking water.
Waxy potatoes for boiling and salad, floury for mash and roasting; starch gelatinises when hot and retrogrades on cooling, which is why potato salad holds together.

Eggs

Coagulation: white 60–65 °C, yolk 65–70 °C, whole egg sets near 70 °C, custard 80–85 °C.
Hard-boiled 9–10 minutes then iced; fresh eggs sink, older eggs peel more easily.
Raw preparations require pasteurised egg because of salmonella risk.

Worked example

2 kg of dried chickpeas at a yield factor of 2.3 gives 4.6 kg cooked. At 120 g per portion that is 4.6 ÷ 0.120 = 38 portions. Cost: 2 kg × €2.40 = €4.80, so €0.126 per portion before oil, aromatics and labour, which must be added to the plate cost.

Traps that cost marks

Adding acid early to legumes and toughening the skins.
Boiling green vegetables with the lid on and losing the colour.
Over-whipping cream into butter.
Taking custard above 85 °C and scrambling it.

Baking, Pastry and Desserts

Baking, Pastry and Desserts tests formulas and precision. Unlike savoury cooking, baking depends on ratios and gluten networks, so the exam asks for baker's percentages, lamination logic, sugar and chocolate stages, and the setting mechanisms behind custards and gels.

Formulas and gluten

Baker's percentage: flour is always 100 %; water 60–70 %, salt 1.8–2 %, fresh yeast 1–2 %, sugar and fat according to style.
Gluten forms from glutenin and gliadin with water and work. Under-mixing gives a short, crumbly texture; over-mixing gives toughness.
Autolyse hydrates the flour; folding builds strength; proof until roughly doubled and springy.

Lamination

Dough and butter block must be at similar cool temperatures, about 4–10 °C.
Three single turns give 3³ = 27 layers; keep the edges square and rest 30 minutes in the fridge between turns.
Butter at 25–30 % of dough weight for croissant and puff pastry.

Sugar, eggs and chocolate

Sugar stages: soft ball 113–118 °C, firm ball 118–121 °C, hard ball 121–130 °C, soft crack 132–143 °C, hard crack 146–154 °C, caramel 160–177 °C.
Crystallisation is controlled with glucose, acid or washing down the pan sides.
Egg foams whip better at room temperature and are stabilised with sugar or acid; fold, never stir.
Chocolate: melt dark to 45–50 °C, cool to 27–28 °C, work at 31–32 °C; milk 30–31 °C; white 29–30 °C.

Dessert families

Baked (tarts, cakes, soufflés), set (custards, mousses, bavarois), frozen (ice cream, sorbet) and hot plated desserts.

Worked example

Lean dough for four loaves at 350 g each is 1400 g, allowing 2 % loss. Total percentage is 100 + 65 + 2 + 2 = 169. Flour = 1400 ÷ 1.69 ≈ 828 g. Water at 65 % = 538 g, salt at 2 % = 16.6 g, fresh yeast at 2 % = 16.6 g. Check: 828 + 538 + 16.6 + 16.6 ≈ 1399 g, which matches the target dough weight.

Traps that cost marks

Measuring by volume instead of weighing.
Opening the oven early and collapsing the rise.
Adding cold butter to a warm dough and breaking the layers.
Seeding chocolate at the wrong temperature and losing the temper.

Plating, Portion Control and Menu Design

Plating, Portion Control and Menu Design tests the commercial side of the plate: consistent portions, controlled costs, plates that look deliberate, and a menu the kitchen can actually produce at a profit. Expect calculation questions plus judgement questions on layout and menu balance.

Portion control

Standard recipe, scales and portion tools: ladles of 30, 60 and 90 ml, and dishers numbered #8 (118 ml), #16 (59 ml), #24 (40 ml) and #40 (24 ml).
Weigh rather than eyeball, and check at the pass; over-portioning by 10 % on a 200 g protein wipes out the margin.
Distinguish EP from AP and record trim, shrinkage and waste.

Plating principles

The plate is a frame: negative space, an off-centre focal point, 3–5 components and height that remains stable.
Contrast colour, texture and temperature; odd numbers read more naturally than even.
Sauce under or beside the food, never flooding the rim; wipe the rim; hot food on a warm plate.
Garnish must be edible and relevant, not decoration.

Menu design

Balance cooking methods and equipment so not everything is grilled or fried at once.
Consider seasonality, allergen spread, cost spread, prep time and the skill level of the brigade.
Menu engineering plots popularity against contribution margin (selling price minus food cost).

Worked example

400 items sold across four dishes. A: 160 sold, margin €7.50. B: 120 sold, €3.00. C: 80 sold, €8.00. D: 40 sold, €2.50. Average sales = 100; popularity threshold = 70 % of average = 70. A is a star (popular, high margin), B a plough horse (popular, low margin), C a puzzle (unpopular, high margin), D a dog (unpopular, low margin). Action: keep A, re-engineer B through price or cost, promote C, remove D.

Traps that cost marks

Costing from the AP price and ignoring garnish, oil and waste.
Overcrowding the plate and losing the focal point.
Writing a menu larger than the brigade and equipment can deliver.
Putting every dish through the same cooking method on the menu.
