21
Q

what can affect the success of a recipe?

A

the fact that imperial and metric are not completely equivalent -> convenient numbers are used

22
Q

what is said to be the most accurate reproducible measuring method?

A

sifting and then spooning flour into measuring cup

23
Q

what is the default method? (3)

A
  • stir flour to break up lumps
  • spoon flour into cup without packing
  • level cup with straight edge of a knife
24
Q

bulky items should be ___ packed

A

lightly packed (rice)

25
Q

brown sugar and solid fats should be ____ packed prior to levelling. why?

A

firmly packed to eliminate air pockets

26
Q

butter and margarine are available in stick of ________ with volume measurements on their wrappers.

A

1/2 cup or 2 cups

27
Q

for larger quantities of liquid ingredients such as honey, molasses, and oil, what measuring tool is used? where should the liquid volume be read at?

A
  • a transparent cup with graduated measurements on the side with a pouring spot and handle
  • read at eye level at the bottom of meniscus
28
Q

how do you remove sticky ingredient from measuring utensil?

A

coat container with oil or warm it with hot water

29
Q

what are the typical metric and imperial measurements of a graduated cup?

A

metric: 250mL, 500mL, 1L, 2L
imperial: 1 cup, 2 cups, 4 cups, 8 cups

30
Q

how do you obtain an accurate reading for a thermometer? how can you increase accuracy of it?

A
  • the bulb must be completely submerged in the food item or liquid
  • calibration increases accuracy
31
Q

the bulb should not touch _____ (2)

A

the sides or bottom of the utensil or bone in meat

32
Q

how do you calibrate a thermometer?

A

put it in hot boiling water, if it doesn’t record 100 degrees C -> correct for it

33
Q

bi-metallic thermometers can be calibrated using _____ (2)

A

a wrench or pliers

34
Q

what are the conversion equations between celsius and Fahrenheit?

A

C=(F-32)/1.8

F=(Cx1.8)+32

35
Q

when using heat, cooking is the transfer of ____ from _____ to ____, causing ____ change in the shape of ____,____,_____.

A

energy from a heat source to food causing physical change in the shape of pro, carbs, fats.

36
Q

what does heating accelerate?

A

the rate at which a chemical reaction takes place

37
Q

how is heat transferred? what is the energy used for? (3)

A
  • from the more energetic (hotter) system to the less energetic (cooler)
  • energy is used to raise temperatures of food being cooked, evaporation and browning reactions
38
Q

____ is a system of measurement that quantify how much energy is in a specific system. what does it depend on (3)?

A
  • temperature

- > it depends on: amount of energy in that body, density, specific heat capacity

39
Q

____ is a measurement of the quantity of molecules there are in a given amount of space.

A

density

40
Q

________ is the amount of energy it takes to raise a given amount of material to a certain temperature. the higher it is for a given material, the ____ energy it takes to raise the temperature of that material by the same number of degrees
-> “willingness” of a substance to change its temperature, the ____ the value, the more easily the temperature changes

A
  • specific heat capacity
  • more
  • lower
41
Q

what are the three source of energy and heat transfer? which is most efficient in heat transfer?

A
  • conduction
  • convection
  • radiation

-> most efficient: conduction

42
Q

____ is the direct transfer of energy from one solid body to another.

A

conduction

43
Q

____ is the transfer of one solid body to another through the intermediary of a fluid - a liquid or a gas. what influences its efficiency?

A

convection - depends on the way fluid flows around food

44
Q

the motion of fluid is referred to as _____

A

convection patterns

45
Q

how does a convection oven work?

A

they have fans that are designed to keep the air inside moving around to promote faster, more even cooking

46
Q

____ is the transfer of energy through space via electromagnetic waves; it doesn’t require any medium from heat transfer. give an example.

A

radiation

eg. broiler

47
Q

how does a microwave work?

A
  • microwaves penetrate through the exterior of the food when heating it (pass through a depth of at least a few cm)
  • they are a form of electro-magnetic radiation.
  • when they are aimed at an object with magnetically charged particles, those particles rapidly flip back and forth creating friction which in turn creates heat
48
Q

what are advantages of microwaves? what are its limitations?

A

advantages: produce less heat, use less electricity than ovens, used to make baked good quickly (average results for regular/rich cakes)
limitations: no browning reactions occur -> over-baking

49
Q

microwaves aren’t good for baking with types of cake?

A

light or angel-type cakes
