Answer

In brown braising, the food is browned in fat first and then cooked slowly in a covered vessel with a small amount of brown stock or sauce. In white braising, the food is cooked without browning, usually with white stock or another pale liquid, to retain a light colour.

Question 1(b)(ii)

Suggest five disadvantages of braising food. (5 marks)

Answer

  • It takes a long time.
  • Long cooking can increase fuel use.
  • Some water-soluble nutrients pass into the cooking liquid.
  • Overcooking can make the food mushy and spoil its texture.
  • The liquid and enclosed cooking can reduce crispness and fresh colour.

Question 1(c)

Explain four ways of enhancing safety in the kitchen. (8 marks)

Answer

  • Keep floors dry and routes clear to reduce slips and collisions.
  • Train staff to use knives and machinery correctly; maintain guards and isolate equipment before cleaning.
  • Handle hot equipment with suitable protection and keep pan handles positioned safely.
  • Maintain gas and electrical installations and keep fire exits and suitable firefighting equipment accessible.

Question 2(a)

Enumerate five points to consider when planning meals for vegetarians. (5 marks)

Answer

  • The type of vegetarian diet and foods excluded.

Answer

  1. Make the scene safe and help the person lie down if they feel faint.

  4. Loosen restrictive clothing, keep a comfortable temperature and give reassurance when the person responds.
  5. Monitor breathing and recovery; seek medical help if recovery is delayed, symptoms recur or an injury or other illness is suspected. Do not give food or drink to an unresponsive person.

Answer

  • Name of the food.
  • Ingredients and relevant allergen information.
  • Net quantity.
  • Date marking and storage instructions.
  • Manufacturer or supplier identification and batch/lot details.

Question 3(b)

Describe three methods of heat transfer as used in cookery. (6 marks)

Answer

  • Conduction: heat travels through direct contact, for example from a hot pan into food.
  • Convection: circulating hot liquid or air carries heat, as in boiling water or a fan oven.
  • Radiation: energy travels as waves from a heat source to the food, as with a radiant grill.

Question 3(c)(i)

State two reasons for each of the following faults in puff pastry: (I) fat oozing out; (II) uneven rise. (2 marks each) (4 marks)

Answer

  • Fat oozing out: fat becomes too warm/soft during rolling; torn dough or inadequate resting exposes fat between layers.
  • Uneven rise: uneven rolling creates unequal layers; crushed or sealed edges from poor cutting prevent even separation.

Question 3(c)(ii)

Outline the procedure for preparing choux pastry. (5 marks)

Answer

  1. Bring measured water and fat to the boil.
  2. Add the sieved flour all at once and stir vigorously.
  3. Cook briefly until a smooth panada forms and leaves the sides of the pan.
  4. Cool slightly, then beat in eggs gradually to a smooth piping consistency.
  5. Pipe or spoon onto a tray and bake until risen, dry and crisp; release steam and cool before filling.

Question 4(a)

Highlight four disadvantages of hard water. (4 marks)

Answer

  • Forms scale in boilers and kettles.
  • Reduces heating efficiency and can damage equipment.
  • Requires more soap and forms scum.
  • Can slow the softening of pulses and affect some beverages or cooked products.

Question 4(b)

State three points to note when using each of the following raising agents: (i) baking powder; (ii) yeast. (3 marks each) (6 marks)

Answer

  • Baking powder: measure accurately; mix evenly with the flour; store dry and use fresh powder so its raising action remains effective.
  • Yeast: use fresh active yeast; use warm rather than hot liquid; allow suitable proofing time and avoid direct contact with concentrated salt.

Answer

  • Customer needs: suit preferences, age, dietary requirements and the occasion.
  • Nutritional balance: combine foods that provide a suitable range of nutrients.
