Question 1

What is the difference between sweating and sautéing vegetables?

Accepted Answer

Sweating uses low heat with fat to soften vegetables without browning; sautéing uses high heat to brown and caramelize the vegetables

Answer

Sweating (suer) cooks vegetables in fat over low to moderate heat to soften them and release moisture without developing colour. Sautéing (sauter) uses high heat with fat to quickly cook and brown vegetables, developing caramelization and Maillard reaction flavours.

Question 2

How does acidic cooking liquid (vinegar, lemon juice) affect the colour of red vegetables like red cabbage?

Accepted Answer

It brightens and stabilizes the red/purple colour

Answer

Red and purple vegetables contain anthocyanin pigments that are pH-sensitive. Acidic environments (vinegar, lemon juice, wine) stabilize these pigments and produce bright red colours. Alkaline environments turn them blue or green. This is why red cabbage recipes traditionally include vinegar or apples.

Question 3

What is a tourné cut and how many sides should it have?

Accepted Answer

A barrel or football-shaped cut with 7 sides, approximately 5 cm (2 inches) long

Answer

A tourné is a classical French knife cut that shapes vegetables into barrel or football-shaped pieces with 7 flat sides, approximately 5 cm (2 inches) long. It is one of the most challenging knife cuts, requiring a tourné (bird's beak) knife and significant practice to master.

Question 4

What is the best cooking method for asparagus to maintain its colour, texture, and nutrients?

Accepted Answer

Blanching or steaming briefly, then shocking in ice water if serving cold, or finishing with a quick sauté

Answer

Asparagus is best cooked briefly using blanching, steaming, or grilling to maintain its vibrant green colour, crisp-tender texture, and nutritional value. If serving cold, shocking in ice water immediately after blanching locks in the colour. A quick sauté or grill adds flavour while preserving texture.

Question 5

What is concassé as a vegetable preparation?

Accepted Answer

Tomatoes that have been peeled, seeded, and roughly chopped

Answer

Concassé (from the French concasser, 'to crush') specifically refers to tomatoes that have been blanched, peeled, cut in half, seeded, and then roughly chopped. Tomato concassé is used as a base for sauces, a garnish for soups and proteins, and as an ingredient in many classical preparations.
