2 us Eggs & Cheese 2 EGGS

3 us Eggs & Cheese 3 EGGS Are an essential kitchen ingredient as they can be utilised in a number of ways. They are perfect cooked & eaten on their own or as part of breakfast, lunch or as a snack. They are also incorporated into baking, desserts, pastry, pasta & noodles. They can be used as a binding agent in stuffing, forcemeats, mayonnaise & other sauces as well as a cooking aid such as coating food for frying, glazing etc. Eggs are a nutritious & affordable food source. In NZ we use predominantly hens eggs although both duck & quail eggs may also be utilised.

4 us Eggs & Cheese 4 Duck & Quail Eggs Quail Egg

5 us Eggs & Cheese 5 Ostrich Eggs The largest egg in the world (equivalent to 24 hens eggs). Eggs weigh 3-6 pounds Can make an omelette for 10 people & take 45 minutes to hard boil. Shell is about 1 / 8 inch thick & therefore good for carving & painting

6 us Eggs & Cheese 6 The Structure of an Egg Shell Membranes Germinal Disc Chalazae Thick White Thin White Air Cell Yolk Yolk Membrane

7 us Eggs & Cheese 7 SHELL the first line of defence against the entry of bacteria can be brown or white (depends on the breed of hen) – nutritional value is the same approximately 8000 to 10,000 tiny pores allow moisture, gases & smells to penetrate through

8 us Eggs & Cheese 8 SHELL MEMBRANES there are two membranes on the inside of the shell one membrane sticks to the shell & one surrounds the white (albumen) the second line of defence against bacteria composed of thin layers of protein fibres

9 us Eggs & Cheese 9 GERMINAL DISC appears as a slight depression on the surface of the yolk the entry for the fertilisation of the egg (commercially produced eggs are NOT fertile)

10 us Eggs & Cheese 10 EGG WHITE there are two layers: thin white & thick white mostly made of water with high quality protein & some minerals represents 2 / 3 of the eggs weight (without shell) when a fresh egg is broken, the thick white (a jelly- like substance) stands up firmly around the yolk the thin white surrounds the thick white and is more watery

11 us Eggs & Cheese 11 CHALAZA a pair of spiral bands that anchor the yolk in the centre of the thick white the fresher the egg the more prominent the chalazas unnoticeable when the egg is cooked

12 us Eggs & Cheese 12 YOLK MEMBRANE (VITELLINE MEMBRANE) surrounds and holds the yolk when pierced, the yolk breaks the fresher the egg the stronger the membrane

13 us Eggs & Cheese 13 YOLK the eggs major source of vitamins and minerals, including protein and essential fatty acids represents 1 / 3 of the eggs weight (without shell) yolk colour ranges from light yellow to deep orange, depending on the hens food (diet)

14 us Eggs & Cheese 14 AIR CELL forms at the wide (blunt) end of the egg as it cools after being laid the fresher the egg the smaller the air cell

15 us Eggs & Cheese 15 QUALITY POINTS FOR EGGS The eggshell should be clean, well-shaped, strong and slightly rough When broken there should be a high proportion of thick white to thin white Yolk should be in the centre, firm, round and of good colour

16 us Eggs & Cheese 16 QUALITY POINTS FOR EGGS Due to changes in the egg over time, the chalazae break causing the yolk to move off centre and the thick white starts to break down becoming thinner. The air cell becomes larger due to evaporation of moisture from the egg.

19 us Eggs & Cheese 19 Common Methods for Cooking Eggs We are going to look at three common methods of cooking eggs: boiling poaching frying

20 us Eggs & Cheese 20 BOILING Is the cooking of food that is covered with a liquid at 100°C. There are two methods for boiling: 1. placing the food into cold liquid, bringing it up to boiling point and then simmering the food for the duration of cooking 2. placing the food into boiling liquid, bringing it back to boiling point & then simmering for the duration of cooking

21 us Eggs & Cheese 21 Cooking times for boiled eggs: Boiled eggs are cooked in the shell Soft-Boiled 3 – 5 minutes Medium: 5 – 7 minutes Hard-Boiled 8 – 10 minutes

22 us Eggs & Cheese 22 For boiled eggs there are quality requirements to ensure that the eggs are cooked properly: no presence of a dark grey-green coating around the yolk; this is an indication the egg has been over-cooked the white should be set, not hard the yolk should be set to desired consistency, solid for hard-boiled & starting to thicken, but not hard, for soft-boiled

23 us Eggs & Cheese 23 POACHING Is cooking food in a liquid maintained between 93°C and 98°C (just under boiling point). Tip: break individual eggs into a saucer, and gently slide into the simmering water. This will also help to prevent the eggs from breaking up.

24 us Eggs & Cheese 24 Poaching For poached eggs, always use the freshest eggs available; the thick albumen will hold its shape better around the yolk than older eggs. Fill a pan with approximate depth of 8cm of water. Place a small amount of vinegar into the water (approx. 15ml [1T]), which helps the proteins in the egg to coagulate faster by preventing the egg white from spreading. bring the poaching liquid to a boil & then reduce to a simmer before adding the eggs (bubbles should not break the surface).

25 us Eggs & Cheese 25 FRYING (shallow) To cook food in direct contact with hot oil, butter or fat.

26 us Eggs & Cheese 26 Frying Break eggs & gently slip into the pan. Immediately reduce heat to low Cook slowly until whites are completely set & yolks begin to thicken but are not hard. Turn eggs gently to cook both sides or add a small amount of water & cover with lid to cook tops of eggs.

27 us Eggs & Cheese 27 CHECK YOUR PROGRESS - EGGS 1. Name two quality point of a fresh egg. 2. How long does it take to boil a hard-boiled egg? 3. Why should you not store eggs near strong smelling items such as onions or garlic? 4. What should be added to the water to assist in the setting of the egg white? 5. What temperature should eggs be poached at?

28 us Eggs & Cheese 28 CHECK YOUR PROGRESS - EGGS 1. Name two quality point of a fresh egg. high proportion of thick white to thin white high sitting, strong egg yolk small air cell clean, unbroken shell fresh smell 2. How long does it take to boil a hard-boiled egg? 8 – 10 minutes 3. Why should you not store eggs near strong smelling items such as onions or garlic? As the egg shell is porous, odours can penetrate through & taint the egg. 4. What should be added to the water to assist in the setting of the egg white? A small amount of vinegar. 5. What temperature should eggs be poached at? °C

29 us Eggs & Cheese 29 CHEESE Is derived from the milk of animals usually cows, goats & sheep. Takes approximately 10 litres of milk to yield 1kg cheese Basically cheese is produced in this way: 1. The milk is soured by the addition of a bacteria culture. 2. Rennet is added which causes the protein (casein) in milk to coagulate (curdle) forming a separation in the curds (semi-solids) & the whey (liquid). 3. The curds are warmed, stirred & allowed to settle so that they whey may be drained off. 4. The curds are broken up by grinding, then salt is added & they are pressed into specially shaped moulds. 5. Once a skin or rind has formed & the cheese is set, they are removed from the moulds & placed into special storage to ripen to the desired maturity. This allows the cheese to develop its distinctive flavouring.

30 us Eggs & Cheese 30 Cheese The process of making cheese varies for each type & this gives each cheese its own distinctive characteristic. These differences depend on the following variations in the cheese-making process: ripening time subjection of the cheese to different temperatures e.g.. cooking the addition or reduction of fat the addition of bacteria cultures the addition of yeasts the addition of moulds the ripening & curing process

31 us Eggs & Cheese 31 FRESH CHEESE After the curds & whey have been separated, the whey is drained. The curds are salted, mixed & some are pressed into moulds. Fresh cheeses are uncooked & unripened. They must be eaten within a short timeframe after manufacture. Some examples of fresh cheese are: Bocconcini Cottage Cheese Cream Cheese Feta Mascarpone Ricotta

32 us Eggs & Cheese 32 SOFT WHITE RIND CHEESE Are neither cooked nor pressed but are shaped in moulds as they drain. Are exposed to an edible bacteria, either by spraying or dipping, which ripens the cheese from the outside in & this produces the smooth velvety white rind. The texture ranges from semi-soft to creamy & spreadable. Some examples of soft white rind cheese are: Aorangi Brie Camembert

33 us Eggs & Cheese 33 SEMI-SOFT CHEESE Are pressed to expel more whey & this produces a more rubbery texture. May be cooked or uncooked & some (Edam & Gouda) are sealed with a coloured wax. Have a sliceable, yet soft consistency Examples of semi-soft cheese include: Edam Young Gouda Havarti Raclette Port Salut

34 us Eggs & Cheese 34 SEMI-HARD CHEESES Are cooked, pressed & ripened although not as long as hard cheeses. Moisture level is relatively low & their texture is firm but not crumbly. Examples of semi-hard cheeses include: Aged Gouda Gruyere Cheddar Emmentale

35 us Eggs & Cheese 35 HARD CHEESE Are cooked at high temperatures, cut, pressed & aged for at least two years. The longer the cheese is held under pressure, the harder, drier & more intense the flavour becomes. Hard cheeses are generally used for grating. Examples of hard cheeses include: Parmesan Pecorino Romano

36 us Eggs & Cheese 36 BLUE VEIN CHEESE Have the mould penicillin added to the milk. During the aging process the cheese is punctured with holes to ensure the penicillin will grow through to the centre of the cheese & the results are veins of flavoursome blue- green mould throughout the cheese. Examples of blue vein cheeses include: Kikorangi Roquefort Stilton

37 us Eggs & Cheese 37 STRETCH CURD CHEESE The special technique of kneading & stretching the curds, after a hot whey bath, give these cheese their pliable consistency. An example of stretch curd cheese is: Mozzarella

38 us Eggs & Cheese 38 STORAGE OF CHEESE If stored incorrectly cheese will not last. Therefore it is important to remember these points: All cheese should be wrapped & stored in the refrigerator. Fresh & soft white rind cheese should be stored in the coldest part of the refrigerator. Hard, semi-hard & semi-soft cheese should be stored in the cheese compartment (warmest area) of the refrigerator. To prevent drying out, cut cheeses should have their cut surface wrapped with waxed paper, greaseproof paper of foil. The rind should not be wrapped, but allowed to breathe. If surface mould appears on hard, semi-hard or semi-soft cheese simply cut away that portion (with a little extra). If mould appears on fresh or soft rind cheeses, throw it out.

39 us Eggs & Cheese 39 QUALITY INDICATORS FOR CHEESE There should be no sign of mildew on the rind of the cheese, as this indicates damp storage conditions. When cut the cheese should not give off an over-strong aroma for the cheese type. There should be no indication of ammonia. Semi-hard & blue vein cheese should not appear dry when cut. Soft white rind cheeses should not appear runny when cut.

40 us Eggs & Cheese 40 QUALITY POINTS FOR CHEESE No Mould on skin/rind Consistency correct for cheese type

41 us Eggs & Cheese 41 FETA A classic Greek cheese traditionally made from sheep or goats milk. It is a white, crumbly rindless cheese commonly found pressed into square cakes. It is cured & stored in its own salty whey brine & has a rich tangy flavour. It ranges in texture from dry to semi-dry.
