A chef de cuisine is costing a pastry menu item. The recipe yields 24 tarts and total ingredient cost is $18.00. With a target food cost of 25%, what should each tart sell for?
Answer: $3.00
Cost per tart is $0.75, and dividing by the 25% target food cost gives a $3.00 selling price.
Why should high-ratio cakes use emulsified (high-ratio) shortening rather than regular butter?
Answer: Its emulsifiers allow the batter to hold more sugar and liquid without breaking
Emulsified shortening contains added emulsifiers that stabilize batters carrying sugar levels exceeding flour weight.
A pastry section experiences crystallized, grainy fondant after cooking. Which practice prevents this defect?
Answer: Washing down the pan sides and avoiding agitation while the syrup cooks
Stray crystals on the pan sides or premature agitation seed the syrup, so washing down and not stirring prevents graininess.
Which fermentation technique improves flavor complexity in artisan breads through extended, refrigerated fermentation?
Answer: Cold retarding the shaped dough overnight
Retarding slows yeast activity while allowing enzymatic and bacterial activity to develop deeper flavor.
When plating a dessert with sauce, crumble, and quenelle components, which principle best guides professional presentation?
Answer: Balance height, texture, color, and negative space with a clear focal point
Professional plating balances contrasting textures, colors, and heights while using negative space to direct focus.
A custard pie filling weeps liquid after baking and chilling. What is the most probable cause?
Answer: Overbaking caused the egg proteins to over-coagulate and squeeze out moisture
Over-coagulated egg proteins tighten and expel water, a defect called syneresis or weeping.
Which storage practice best maintains quality of finished laminated pastries such as croissants for next-day service?
Answer: Freeze them baked and refresh briefly in a hot oven before service
Freezing halts staling and a brief oven refresh restores crispness, while refrigeration accelerates starch retrogradation.
