Page-by-Page Notes: Eggs, Dishes, and Cereals & Starch Dishes

Page 1

• Market forms of eggs: Fresh, Dried, Frozen.
• Fresh eggs (shell) sold individually, by dozen, or in trays of 36.
• Frozen eggs: pasteurized, whole eggs with extra yolks/whites; thaw before use.
• Dried eggs: whites mainly for merengue; used as ingredients in food industry; not commonly sold to consumers.
• Processed forms: bulk/liquid whole eggs (may include extra yolks), egg whites, and egg yolks.
• Pasteurized products used where raw eggs are avoided (dressings, eggnog, desserts); available liquid or frozen.
• Frozen egg products used as ingredients by processors.
• Yolk-containing products often have salt, sugar, or corn syrup to prevent gelation/viscosity increases during freezing; packaged in $30 ext{ lb}$ containers and in $4 ext{ lb}, 5 ext{ lb}, 8 ext{ lb}, 10 ext{ lb}$ pouches or waxed/plastic cartons.
• Dried powdered eggs sold for some baked goods or circumstances.
• Egg substitutes: either egg-free or derived from whites with yolks substituted by dairy/vegetable products; important for reduced-cholesterol diets.

• Uses of eggs in culinary arts: versatile protein and ingredient across courses; can be dry- or moist-heat cooked; functional in many forms.
• Effect of heat on eggs:
  • Coagulation temps: white $60 ext{–}65^{\u00b0}C$; yolk $65 ext{–}70^{\u00b0}C$.
  • Overcooking leads to water expulsion, shrinkage, tough texture.
• Greenish discoloration at yolk-white interface when overcooked due to iron in yolk reacting with hydrogen sulfide from ferrous sulfide; promoted by high temperature and long cooking; prevented by immediate cooling (e.g., cold water plunge).
• Uses of eggs (selected):
  1) Cooked and served as is (in shell: soft/hard-cooked; poached; fried; scrambled; omelet).
  2) Eggs as emulsifier: lecithin and lysolecithin in yolk enable emulsification; polar end water-loving, non-polar end fat-loving; prevents oil droplets from coalescing.

3. Binding, thickening, and gelling

• Eggs provide proteins that denature with heat; whole egg requires lower coagulation temps, yielding a stiffer gel.
• Sugar raises coagulation temp, giving a softer/weaker gel; softer gels with scalded milk and acid.
• Custards: Bain-Marie/double boiler/steam to avoid boiling and porosity; soft custards by constant stirring.

3. Foam

• Beaten eggs: albumen denatures; air is trapped and volume increases.
• With whites only: bright white, soft peaks; whole eggs/yolks: pale yellow, volume increases but less; over-beating causes liquid to drain and foam to break.
• Stability: soft stage most stable; stiff stage yields max volume.
• Foam formation stages:
  A. Frothy: large, flowing bubbles
  B. Soft foam: smaller, numerous air cells; white turns whiter; soft peaks form
  C. Stiff foam: peaks hold shape; bowl tip shows gloss
  D. Dry: gloss disappears; specks appear

Page 4

• Factors in foam formation (leavening):
  a) Beating time/temperature: volume and stability rise then fall; refrigerated eggs are harder to beat.
  b) Room temperature eggs whip better; higher volume, finer texture.
  c) Whole eggs/yolk require more beating.
  d) Stored eggs foam faster but with smaller volume than fresh.
  e) Acids (e.g., cream of tartar) increase stability but too early delays foam formation.
  f) Sugar increases stability but delays foam formation; add after foaming starts and soft peaks form; retards denaturation of white.
  g) Soda increases stability/volume.
  h) Salt lowers foam quality.
  i) Duck eggs foam poorly (lack ovumucin).
  j) Dilution with water increases volume but reduces foam; can cause syneresis in meringues.
  k) Applications: as leavening (angel/sponges/chiffon), as meringue (soft for toppings; hard for confections), and as structural/textural agents (soufflés, foam cakes, popovers).
• Coloring/flavoring agents: egg products include Balut, Pidan, Century, Pickled eggs.

Page 5

• Egg dishes and shell-eggs: various cooking methods; shell eggs should be simmered, not boiled, to avoid overcoagulation; optimum shell-cooking time $20 ext{–}25 ext{ minutes}$; warm refrigerated eggs to ambient before cooking; use room-temp water for boiling.
• Greenish yolks: iron sulfide formation; high albumen pH or excessive cooking can cause it.
• Eggs out of shell: poaching, frying, scrambling, omelets.
• As thickening/binder: yolks/whites convert hydrophilic colloids to hydrophobic gels when heated; coagulation of egg白 starts at $60 ext{–}62^{\u00b0}C$ for white and $65^{\u00b0}C$+ for yolk.

Page 6

• Eggs as leavening agents: used in sponge cakes, chiffon, meringues, soufflés; air incorporation during beating; avoid overbeating (stretches albumen, can lead to dryness).
• Functional foods: eggs contain lutein and zeaxanthin reducing cataracts/macular degeneration; designer foods may include omega-3 fatty acids and vitamin E.

Page 7

• Variety of egg dishes (shell cooking):
  • Coddled eggs: simmer 30 seconds after placing cold eggs in simmering water.
  • Soft-cooked: 3–4 minutes.
  • Medium-cooked: 5–7 minutes.
• Poached eggs: slide shelled eggs into barely simmering water; keep shape; freshness improves yolk center and white integrity.
• Poached eggs can be made ahead and held; reheat in simmering water.

Page 8

• Poached eggs standards: bright, shiny appearance; compact, rounded shape; firm but tender whites; warm, liquid yolk.
• Critical factors: egg quality, temperature, liquid amount, method of introducing egg.
• Fried eggs: require fresh eggs, correct heat, adequate fat, and skill; served sunny side up or over.
• Fried-egg standards: white glossy and set but not browned; yolk set to desired doneness; compact, high; yolk often slightly fluid under a film of white; overall glossy, crispy edges for some styles.

• Serve hot, fresh, moist; use nonstick pans when possible; reserve dedicated pans for eggs.
• Flavor variations include herbs, cheese, ham, vegetables, smoked fish, sausage.
• A good scrambled egg should be fully coagulated but not tough or burnt.

Page 27

• LESSON 1: PREPARE EGG DISHES (heading only; content likely hands-on practice for egg dishes).

Page 29

• The rolled (French-style) omelets start like scrambled eggs; as the eggs set, they roll; American omelet is folded; two other styles exist (beaten mixture cooked over direct heat or in an oven).
• Fresh eggs preferred for shape; fillings added at the right time to ensure hot and fully cooked fillings.
• Omelet fillings: cheese, sautéed vegetables, potatoes, meats, smoked fish; cheeses melt with heat; fillings added just before rolling/folding.
• Two factors for quality omelets:
  1) High heat: omelet cooks fast; internal temp stays controlled.
  2) Conditioned pan: sloping sides, appropriate size, well-seasoned to prevent sticking.

Page 30

• Pan requirements for omelets: sloping sides, correct size, well-seasoned/conditioned to avoid sticking.

Page 33

• Egg-handling tips:
  • Purchasing: avoid dirty/cracked/outdated eggs.
  • Storage: keep at 45^{b0}F or below; use closed containers; store away from strong odors; refrigerate leftovers in shallow containers; keep drippings away from eggs.
  • Preparation: keep refrigerated before/after cooking; maintain cleanliness; use clean, uncracked eggs; cook thoroughly; wash containers; use egg separator.
  • Service/Transport: serve promptly; keep cold foods cold, hot foods hot; use ice/cold packs during transport; avoid raw eggs or foods with raw eggs.

Page 34

• LESSON 2: PREPARE CEREALS AND STARCH DISHES
• Overview: cereals are starchy grains (rice, wheat, corn as main cereals); starch is major carbohydrate in cereals/tubers; starch used in food prep (puddings, gravies, sauces); starch is second most abundant organic substance on earth.
• Major starch sources: cereals (corn, wheat, rice, sorghum, oats), legumes, roots/tubers (potato, sweet potato, arrowroot, cassava/tapioca).
• Common starches: corn starch, potato starch, tapioca (cassava).
• Starch types: native/natural; modified; purified via wet milling.

Page 35

• The starch molecule: polysaccharide of glucose; two fractions: amylose (long, linear, 500–2,000 glucose units) and amylopectin (highly branched).
• Amylose contributes gelling; amylopectin contributes to thickening but not gel formation.
• Natural starches contain both; amylose % varies by source (corn, wheat, rice ~16–28% depending on source; tapioca/potato lower).
• Starch granule structure: hilum center; birefringence (Maltese cross under polarized light) disappears on heating; granule size/shapes differ by source.
• Composition snapshots for cassava, wheat, corn, potato starches.
• Gelatinization/composition relations: granule hydration/swelling, loss of birefringence, increased clarity; dissolution and diffusion upon heating and subsequent cooling.

Page 36

• Gelatinization/process: starch granules swell and absorb water; disruption of organized granule structure; viscosity increases with swelling and rupture; after heating and stirring, more granules rupture and diffusion occurs.
• Thermal processes: heating leads to gelatinization; as you remove heat, retrogradation may occur (gel becomes paste-like).

Page 37

• Sugar’s influence on gelatinization: sugar competes for water; different sweeteners affect temp and rate of gelatinization; harmful effects depend on water competition.
• Retrogadation (retrogradation): amylose chains re-associate on cooling to form a gel; crystalline order reappears.
• Syneresis: liquid oozing from set gels (puddings, jellies, custards, gelatin, agar).
• Dextrinization: formation of dextrins by dry roasting or heating; hydrolysis of starches during cooking/storage; prolonged heating with acid hydrolyzes starch, reducing viscosity.

Page 38

• Functional properties of starches:
  1) Thickeners in gravies, sauces, puddings; gel formation when cooked.
  2) Colloidal stabilizers.
  3) Moisture retainer.
  4) Gel-forming agents.
  5) Binders.
  6) Packaging/filler roles in processed meats; flavor carriers (traps fats/oils and flavors).
• Starch sources for processed meats and other industries.
• Cereals and whole grains: not empty calories; encourage daily servings; enriched/restored cereals provide nutrients (thiamine, niacin, riboflavin, iron).

Page 39

• Nutritional significance of noodles/pasta (alimentary paste): noodles/pasta are starch-rich with added fibers; may contain some protein and fat; includes RS (resistant starch).
• Typical nutritive values listed for water, protein, fat, carbs, minerals and vitamins; examples of noodle/pasta types.

Page 40

• Learning Outcome 3: Store starch and cereal dishes.
• Importance: proper storage to control bacterial growth/contamination; FIFO (First In, First Out) practice; date labeling for expiry/receipts/storage.
• Pasta storage:
  • Dry pasta: store in airtight container; cool, dry place; indefinite shelf life but best quality within 2 years.
  • Dried egg noodles: up to 6 months.

Page 41

• Cooked pasta storage:
  • Drain thoroughly; coat with small amount of oil to prevent sticking; refrigerate in airtight container 3–5 days.
  • Sauce stored separately; if stored together with sauce, shelf life shortened (1–2 days).
  • Frozen cooked pasta can be used for ~3 months; thaw in fridge.
  • Fresh pasta: best used same day; if longer, refrigerate 2–3 days; freeze stuffed pastas up to 3 months; frozen pasta doesn't require thawing before cooking; increase cooking time slightly.
  • Fresh homemade pasta can be dried for later storage; drying time varies by type; proper storage in cool, dry place.

Page 42

• Learning Outcome 4: Present Egg Dishes (overview of plating and presentation principles).
• Seven simple plating guidelines: proper table setting, plate choice, visual balance/clock-face arrangement (carbs at 11, vegetables at 2, protein at 6), height variation, odd-number groupings, color/texture balance, height and garnish considerations.

Page 43

• Continuation of plating tips: plate height, garnish edibility and relevance, visual harmony with the main dish.

Page 44

• Additional plating ideas: height variety, color contrast, edible garnish utility; example arrangements for rice, protein, and vegetables; garnish to enhance flavor, not overpower the dish.
