415A baking, pastry and desserts practice questions.

Five free practice questions on baking, pastry and desserts: block M of the Red Seal 415A Cook exam, about 10 of its 150 questions. They are in the exam's format: four options, one correct answer. Answer each one before opening the explanation. No account, no email.

01The questions

1. Recall · Cooks dough-based products

   A school food-service kitchen bakes lean sandwich loaves. Which internal temperature indicates a lean yeast loaf is fully baked?

   1. About 63 °C
   2. About 74 °C
   3. About 82 °C
   4. About 93–99 °C
   Show the answer

   D. Correct. Lean breads are typically done at about 93–99 °C in the centre (enriched breads such as brioche lower, about 88–93 °C). Confirm with the sensory checks: an even, well-coloured crust and a hollow sound when the bottom is tapped.

   Why not the others

   A. 63 °C is Health Canada's minimum for whole cuts of beef and lamb (medium-rare), not a bread doneness. A loaf at 63 °C has a raw, gummy centre because the starch has not fully set.

   B. 74 °C is the reheating and poultry-piece temperature. Bread at 74 °C is still underbaked: the crumb is doughy and will collapse or turn gummy as it cools.

   C. 82 °C is the whole-poultry and crème-anglaise number. It is still short for a lean loaf; enriched doughs finish around 88–93 °C and lean doughs higher still.

2. Procedural · Assembles savoury and sweet pastries and pies

   A catering cook is assembling spanakopita triangles from frozen phyllo. How should the phyllo be handled?

   1. Thaw in the fridge, keep it covered, brush each layer with fat
   2. Mist each sheet lightly with water to keep it supple
   3. Thaw it on the bench, then work with the sheets uncovered
   4. Stack the sheets dry and brush butter only on the top layer
   Show the answer

   A. Correct. Phyllo is thawed in the refrigerator in its wrapper, and the stack is kept under film and a lightly damp towel while working. Brushing each sheet with melted butter or oil keeps the layers separate so they bake up crisp and flaky.

   Why not the others

   B. Water turns phyllo gummy and makes the sheets stick and tear; it also steams rather than crisps in the oven. The layers are brushed with melted butter or oil, not water.

   C. Room-temperature thawing causes condensation that glues the sheets together, and uncovered phyllo dries and cracks within minutes. Thaw it in the refrigerator and keep the sheets covered.

   D. Dry inner sheets bake into papery, stuck-together layers that neither separate nor brown. Fat brushed between every layer is what makes phyllo flake.

3. Procedural · Cooks batter-based products

   For a carvery, a cook makes Yorkshire puddings from a rested batter of eggs, flour and milk. Which method gives tall, crisp puddings?

   1. Pour the batter into cold greased tins and bake at 160 °C
   2. Heat fat in the tins until very hot, fill, and bake at about 220 °C
   3. Bake at 220 °C, opening the oven midway to let the steam out
   4. Add baking powder to the batter and bake at 180 °C
   Show the answer

   B. Correct. Yorkshire puddings and popovers are leavened by steam. Batter hitting very hot fat starts cooking and puffing at once, and a hot oven (about 220 °C as typical) keeps the steam coming until the egg sets the walls. Keep the door shut until they are firm and deep golden.

   Why not the others

   A. A cold tin and a moderate oven heat the batter slowly, so it sets before enough steam forms. Yorkshire pudding rises on steam and needs a very hot start; this gives flat, heavy puddings.

   C. Opening the door before the walls set drops the oven temperature and lets the puddings collapse. The steam is what lifts them; any venting belongs at the end, once they are firm.

   D. The classic batter has no chemical leavener; steam from the eggs and milk does the lifting. Baking powder and a moderate oven give a cake-like, lower pudding instead of a tall, hollow, crisp one.

4. Procedural · Processes ingredients for creams, mousses, frozen desserts, fillings, icings, toppings and sugar works

   A banquet pastry cook is making 4 L of vanilla crème anglaise. The yolks and sugar have been tempered with the hot milk and cream and returned to low heat. How is the sauce finished?

   1. Bring it to a full boil to thicken it, then strain
   2. Stir until it reaches 70 °C, then cool it at room temperature
   3. Stir to 82–85 °C until nappe, then strain into a bowl over ice
   4. Whisk hard over high heat until it froths and thickens
   Show the answer

   C. Correct. Stirred constantly over low heat, the yolks thicken the sauce to nappe (it coats the back of a spoon and holds a line) at about 82–85 °C. Straining into a bowl set in ice stops the cooking and starts rapid cooling; hold it at 4 °C or lower.

   Why not the others

   A. Crème anglaise has no starch to protect the yolks, so boiling curdles it into sweet scrambled egg. Boiling is the rule for pastry cream, which does contain starch.

   B. At 70 °C the sauce has not reached nappe and will be thin; cooling it slowly at room temperature also holds an egg-and-dairy sauce in the danger zone. Cook to 82–85 °C and chill fast.

   D. High heat overshoots the setting range and curdles the yolks at the base of the pot. Whisking to a froth over a bain-marie is the sabayon method; anglaise is stirred gently over low heat.

5. Recall · Processes chocolate

   A hotel chocolate station tempers dark couverture by tabling on a marble slab. Which temperature curve is typical for dark chocolate?

   1. 60 °C melt, cool to 40 °C, work at 45 °C
   2. 45–50 °C melt, cool to 27–28 °C, work at 31–32 °C
   3. 45 °C melt, cool to 25–26 °C, work at 28–29 °C
   4. 35 °C melt, cool to 20 °C, work at 25 °C
   Show the answer

   B. Correct. Melting to 45–50 °C erases all crystals; tabling on marble cools it to 27–28 °C, where stable beta (form V) crystals start to form; bringing it back to 31–32 °C melts the unstable ones. Test a smear: it should set glossy with a clean snap in a few minutes. Milk is typically worked at 29–30 °C.

   Why not the others

   A. 60 °C risks scorching and thickening the chocolate, and at 40–45 °C no stable crystals can form, so it is never tempered: it sets soft and streaky with fat bloom.

   C. This is the typical curve for white chocolate, which has no cocoa solids and more milk fat. Dark chocolate worked at 28–29 °C is too thick and still carries unstable crystals; it is worked warmer, at 31–32 °C.

   D. 35 °C is not hot enough to melt out every existing crystal, and 20–25 °C is far too cold: the chocolate thickens, forms unstable crystals and sets dull and soft. Dark is melted at 45–50 °C.

02Answer key

03What block M covers

This block covers baking and pastry. It includes bread flour and yeast, laminated doughs such as croissant and puff, choux paste, quick breads and muffins, genoise and Yorkshire puddings, sorbets, Italian meringue, crème anglaise, pastry cream and crème brûlée, cake assembly, pie dough, blind baking, phyllo, tourtière, and chocolate tempering and bloom.

The Red Seal Occupational Standard names this block “Sweet and savoury baked goods and desserts”. It carries 6.7% of the exam, about 10 of the 150 questions, split across six tasks. The share column is each task's weight within the block, as the standard publishes it.

04What the questions turn on

Leaveners and mixing

Baking soda needs an acid such as buttermilk to react; without it the rise is poor and the taste soapy and metallic. Muffin batter is folded only until the flour is moistened, which keeps gluten low and the crumb tender.

Anglaise versus pastry cream

Crème anglaise thickens to nappe at 82 to 85 °C and must never boil. Pastry cream contains starch, so it is boiled for about a minute to gelatinize the starch and destroy a yolk enzyme that would thin it.

Bake choux until dry

Choux keeps its shape only once its walls are baked firm and dry. Golden is not done: pulled early, the steam condenses and the puffs collapse. Lower the oven to dry them and pierce each one to vent the steam.

Tempering and bloom

Dark chocolate is melted to 45 to 50 °C, cooled to 27 to 28 °C and worked at 31 to 32 °C. Cold chocolate moved into warm, humid air gets sugar bloom, so store it dry at about 15 to 18 °C.
