Question 1

What is 'bloom' in gelatin, and why is it necessary?

Accepted Answer

Hydrating gelatin in cold liquid before heating to ensure even dissolution

Answer

Blooming allows gelatin granules to absorb cold water and swell, ensuring they dissolve evenly without clumping when heat is applied.

Question 2

What is the role of invert sugar (trimoline) in confections and ice cream?

Accepted Answer

Prevents crystallization and retains moisture

Answer

Invert sugar inhibits crystallization of sucrose and is highly hygroscopic, keeping confections and ice cream smoother and softer over time.

Question 3

What is the difference between cake flour and all-purpose flour in terms of protein content?

Accepted Answer

Cake flour has 7–8% protein; all-purpose has 10–12%

Answer

Cake flour contains approximately 7–8% protein compared to all-purpose flour's 10–12%, resulting in less gluten development and a more tender crumb.

Question 4

Which type of icing is made by combining boiled sugar syrup with Italian meringue and butter?

Accepted Answer

Italian meringue buttercream

Answer

Italian meringue buttercream is made by streaming hot sugar syrup (240°F) into whipped egg whites to form meringue, then beating in softened butter.

Question 5

What is 'scoring' a bread loaf, and what does it control?

Accepted Answer

Slashing the surface to control oven spring and direct expansion

Answer

Scoring (slashing) creates intentional weak points in the crust, directing expansion upward during oven spring rather than causing uncontrolled bursting.
