Advanced Culinary Techniques Flashcards

During a busy service, a hollandaise sauce has become too thick and is beginning to break. What should the chef do first?

Answer: Whisk in a small amount of warm water to loosen and re-stabilize the emulsion

A few drops of warm water thin the emulsion and help re-disperse the fat before it fully separates.

What is the key difference between a braise and a stew in classical technique?

Answer: Braising uses larger cuts partially submerged; stewing uses small cuts fully submerged

Braises feature large pieces cooked partially covered in liquid, while stews use bite-size pieces fully covered.

Transglutaminase ('meat glue') is used in advanced kitchens primarily to do what?

Answer: Bond proteins together, allowing seamless attachment of different meat pieces

Transglutaminase catalyzes bonds between proteins, letting chefs fuse pieces of meat or fish into uniform portions.

Why is a swiss meringue considered more stable than a french meringue?

Answer: The whites and sugar are warmed together, dissolving the sugar and partially cooking the proteins

Heating whites and sugar over a bain-marie before whipping dissolves the sugar and sets a denser, more stable foam.

A chef smoking salmon at 80°F (27°C) for several hours is using which method?

Answer: Cold smoking, which flavors the fish without cooking it

Cold smoking occurs below about 90°F, imparting smoke flavor while leaving the fish raw-textured, which is why curing beforehand is critical.

What role does the pincage step play when building a classic espagnole sauce?

Answer: Caramelizing tomato paste to deepen color and remove raw bitterness

Pincage means cooking tomato paste until rust-colored, developing sweetness and depth before liquid is added.

When butchering a whole flatfish for fillets, how many fillets are typically produced?
