Terminology within Starch Cookery:

Slurries:

Uncooked mixtures of water and starch

Sols:

Thickened liquids (pourable)
Ex. Muffin or pancake batter

Pastes:

Thickened mixtures of starch & liquid with

little flow

Gels:

Starch mixtures that are rigid
Hydrogen bonding forms a JUNCTION

Terminology within Starch Cookery:

Retrogradation:

Firming of a gel during cooling and

standing

Good- need gel to form

Bad-Cracks in gravy

Syneresis:

Water leaking from a gel

Consider when product will be

served

And Even More…
Terminology within Starch Cookery:

Viscosity:

Resistance of a mixture to flow

Larger molecules more difficult to move

Measures the thickening ability of a starch

Stability:

Ability of a thickened mixture to remain

constant over time

Stable sauce can be frozen and/or reheated

Thickening Sauces with
Starch

Cold Water Paste

Quickly stirring starch with cold water until

paste is formed

Thicken soup broth or gravy

Starch & Sugar

Combining starch and sugar, gradually

adding liquid

Should sound familiar

Thickening Sauces with Starch

Starch & Fat

BEURRE MANIE

Mixture of equal amounts by weight of flour and

butter

Added to hot soups to thicken broth
Disperses starch granules with little risk of clumping

ROUX

Mixture of equal amounts by weight of flour and fat

cooked to a varying degree of doneness

Needs low heat and constant stirring
Extended heating will reduce thickening ability of the

starch

I’m done, I promise… (for now)
Terminology within Starch Cookery:

Opacity:

How much an object blocks light

Translucency:

How much light passes through an object

Modified Starches:

also called starch derivatives, are prepared

by physically, enzymatically, or chemically
treating native starch to change its properties.

Examples:from potato, corn, rice, tapioca, and wheat
