Question 1

What is the standard knife cut known as a brunoise?

Accepted Answer

A 3 mm (1/8 inch) cube

Answer

A brunoise is a precision knife cut producing 3 mm × 3 mm × 3 mm (1/8 inch) cubes. It is achieved by first cutting a fine julienne (3 mm × 3 mm × 5 cm), then cutting across the julienne at 3 mm intervals. It is used as a garnish for soups, sauces, and plated dishes.

Question 2

Why should green vegetables be cooked in a large volume of boiling salted water with the lid off?

Accepted Answer

To maintain their bright green colour by diluting plant acids and allowing volatile acids to escape as steam

Answer

Cooking green vegetables in abundant boiling salted water with the lid off maintains their bright colour. The large volume of water dilutes plant acids that cause colour change, the boiling temperature quickly deactivates the enzyme chlorophyllase, and leaving the lid off allows volatile acids to escape as steam rather than condensing back into the water.

Question 3

What is the difference between a julienne and a chiffonade cut?

Accepted Answer

Julienne produces thin matchstick strips from firm vegetables; chiffonade produces thin ribbons by rolling and slicing leafy vegetables or herbs

Answer

Julienne produces thin matchstick strips (3 mm × 3 mm × 5 cm) from firm vegetables like carrots or celery by squaring off the vegetable and making precise cuts. Chiffonade produces thin ribbons by stacking leafy herbs or vegetables (like basil or spinach), rolling them tightly, and slicing across the roll.

Question 4

What happens to root vegetables if they are started in boiling water instead of cold water?

Accepted Answer

The exterior overcooks and becomes mushy while the interior remains undercooked

Answer

Root vegetables (potatoes, carrots, turnips, beets) should be started in cold water because their dense structure requires gradual, even heat penetration. Starting in boiling water cooks the exterior too rapidly, resulting in a mushy outside while the centre remains raw or undercooked.

Question 5

What is the proper way to store fresh herbs to maximize their shelf life?

Accepted Answer

Trim stems, place upright in a container of water (like flowers), cover loosely, and refrigerate — or wrap in a damp paper towel in a perforated bag

Answer

Tender herbs (cilantro, parsley, basil) last longest when stems are trimmed and placed in a container of water, covered loosely with a plastic bag, and refrigerated (except basil, which prefers room temperature). Alternatively, wrapping in a damp paper towel inside a partially open bag keeps them hydrated without excess moisture.
