Cards

Term
How does heating affect foods?
Definition

~destroys illness causing micro-organisms

 

~alters a food's texture, taste, odor, and appearance

 

 

Term
define moist-heat preparation
Definition

heat is transfered by water, water-based liquid, or steam

 

softens fiborus protien and cellulose making it more tender

 

liquid heats the foods and contributes to flavor, color, texture, and appearance

 

downside: vitamins and minerals can be lost through movement into liquid

Term
name the methods of moist heat preparations
Definition

scalding, poaching, simmering, stewing, braising, boiling, steaming, microwaving(uses both dry and moist)

 

these heating methods can reach up to 212F

Term
scalding
Definition

~150F

 

~visually seen by large but still bubbles sitting on the bottom and sides of the pan

Term
poaching
Definition

~160F

 

~food is partially or totally immersed in water

 

~used for eggs and fish

 

 

Term
simmering
Definition

~180F

 

~more gentle than boiling

 

~slowly rising bubbles that barely break the surface

Term
stewing
Definition

~simmering ingedients in a small-moderate amount of liquid(liquid usually becomes a sauce as food cooks)

 

~taste better the day after it is made

Term
braising
Definition

similar to stewing, flavors blend and intensify

 

usually used for larger cuts of meat than stewing

Term
boiling
Definition

bring liquid to rolling boil to add food evenly then return to boil

 

used for tough-textured veggies and dried pasta/beans

 

two types:

parboiling=food is boiled partially then removed for later cooking or a different method

 

blanching=dipping food breifly in boiling water. sets colors of veggies, loosens skin on foods, destroys enzymes that lead to deterioration  

Term
steaming
Definition

this method is best for cooked veggies because it retains texture, color, taste, and nutrients

 

indirect technique is called papillote: where food is wrapped in foil or parchment paper before baking

Term
microwaving
Definition

incorporates moist(steam) and dry(radiation) heat methods

 

the form of radiation is aimed at the water in a food/beverage

Term
what are the types of dry-heat methods?
Definition

baking, roasting, broiling, grilling, barbequing, and frying 

 

these types of heating methods can reach up to 500F

 

heat is transfered by air, radition, fat, and metal

Term
baking
Definition

heating food by hot air in an oven

 

can be affected by:

rack position= middle is most desirable, multiple dishes should be scattered and not directly on top of each other

pan color=shiney reflects heat(cookies/cakes), dark absorbs heat(breads/pies), glass heats more rapidly

Term
roasting
Definition

type of "baking" usually applied to meats/poultry

 

meats are often basted

 

some meats are seared or cooked at high heats initially then reduced to normal temp. adds texture, color, and flavor but dries meat out

Term
broiling
Definition

food is cooked below a direct heat source

 

food is cooked at very high temp for a short amount of time

 

only tender meat/fish/pourty can be broiled

 

temp is adjusted by moving the rack closer(for thinner cuts) or further(thicker cuts)

Term
grilling
Definition
food is cooked above a direct heat source
Term
barbequeing
Definition

foods are slow cooked over a longer period of time and are usually covered in a sauce

 

temp is regulated by adjusting intensity of heat source

Term
frying
Definition

heating foods in fat

 

types include:

suatéing & stir-frying= use the least amount of fat

pan-broiling= fat is cooked out of meat in frying pan and poured out of pan

 pan-frying=same as pan-broiling except fat in left in pan and used to lightly coat meat

deep-frying=uses most amount of fat, food is covered with fat

Term
what are the four types of heat transfer?
Definition

conduction= direct transfer of heat from one substance to another

 

convection= transfer of heat by moving air/liquid currents through/around food

 

radiation= transfer of heat energy in form of waves of particles moving from source outward

 

induction= transfer of energy without direct contact using coils

Term
name the various types of heat measurement
Definition

use of temperatures scales(F, C, K or kelvins)

 

measurment of kinetic energy via molecular movement= heat speeds up movement, cold slows down movement

 

measure using freezing(32F) and boiling(212F) points

 

measurement using calories

Term
knives
Definition

Chef's or kitchen knife most frequently used

 

position with base of blade between thumb and forefinger and other fingers curled around handle, fingers holding food are curled in

 

position of food and grip affects degree and control of leverage

 

light cutting tasks are done using a pairing knife or the tip of the blade on a chef's knife

 

harder tasks are done using base of chef's blade

Term
describe the various cutlery styles
Definition

slice= to move the food under the blade while keeping the tip of the blade on the cutting board

 

julienne= food is cut into stick shape

 

Shred= cut leafy veggies into thin strips

 

dice= cut food into even-sized cubes

 

mince= chop food into very fine pieces

 

peel= to remove the skin

Term
what are the 3 steps in measuring?
Definition

approximate the amount of of required food

 

select the right measuring utensil

 

use an accurate measuring technique

Term
what techniques are used to measure different types of ingredients
Definition

liquids= transparent graduated measuring cups with pouring lips, make sure cup is on flat surface and to read at the meniscus

 

eggs= range in size, standard is large egg(2oz)

 

fat= for liquids use measuring cups, for solids warm the fat and push into fractional measuring cups

 

sugar= differs based on type:

granulated sugar=pour or spoon

brown sugar= pack into dry cup

powdered= sift then spoon or into dry cup

 

flour= sift and spoon into dry cup

Term
describe the different mixing techniques
Definition

stir= mixing all ingredients together w/ spoon using circular motion

 

beat= ingredients moved vigoruosly up/down, back/forth, round and round until smooth

 

blend= ingredients are mixed so thuroughly they become one

 

bind= ingredients adhere to each other(breading and fish)

 

cream= fat and sugar are beaten together until they become light and airy

 

whip= air is incorporated into foods through very vigorous mixing

 

fold= one ingredient is gently incorporated into another

Term
describe the conventional creaming mixing method
Definition

cream fat and sugar together

 

then add eggs one at a time

 

next add dry ingredients in small portions

Term
describe the convetional sponge/meringue mixing method
Definition
same as creaming method except a portion of the sugar is mixed with a beaten egg and folded into batter at the end of mixing
Term
describe the single stage or dump method
Definition

add dry ingredients

then part of milk and flavorings

stir

add eggs and remaining liquids

add mix

Term
describe the pastry blend method
Definition

the fat is cut into the dry mixture either with mixer or knives in a scissor-like action

 

then moist ingredients are gradually added to the mixture

Term
describe the biscut mixing method
Definition

all dry ingredients are combined

fat is cut into dry

liquid added last

mixed just until moist

Term
describe the muffin mixing method
Definition

dry and moist ingredients mixed separately

then combined and blended just until moist

Term
what is the difference between a seasoning and a flavoring?
Definition

seasoning= any compund that enhances the flavors already in a food

 

flavoring= a substance that adds a new flavor not already present in food

Term

Definition

it should only be added to foods in small increments

 

types of include sea salt, rock salt, kosher salt, and flavored salts

 

used as:

flavor enhancer

preservative

binder

texture enhancer

color aid

control agent for yeast and bacteria

Term
what is the difference between an herb and a spice?
Definition

herbs= a plant leaf usually valued for its flavor or scent

 

spice= derives from friut, flower,seeds, bark, roots

 

both can be purchased whole, ground, or crushed and if dried should be stored below 60F and kept away from air, light, and heat. also both should be replaced every 12 months
