CSA Cake Decoration & Design 3 — Questions and Answers
Question 1: In cake design, what is a 'fault line' cake?
- A cake that has cracked during baking and been patched with buttercream
- A decorative style featuring an exposed mid-section filled with sprinkles or candies between frosted upper and lower portions (Correct answer)
- A tiered cake where tiers are offset at an angle to create a leaning effect
- A cake slice display technique using clear acrylic panels
Correct answer: A decorative style featuring an exposed mid-section filled with sprinkles or candies between frosted upper and lower portions
A fault line cake intentionally leaves a band of the cake's midsection bare and filled with decorative elements, flanked by frosted sections above and below.
Question 2: When painting edible gold leaf onto a cake, what surface preparation is required?
- The surface must be completely dry and matte
- The surface must be slightly tacky so the gold leaf adheres (Correct answer)
- The surface must be chilled to below 40°F before application
- The surface should be coated with piping gel mixed with luster dust first
Correct answer: The surface must be slightly tacky so the gold leaf adheres
Gold leaf requires a slightly sticky surface — such as fresh buttercream or a thin layer of piping gel — to bond properly without crumbling.
Question 3: What is the standard ratio of water to gum paste powder when mixing gum paste from scratch?
- Follow package instructions, as ratios vary by brand and humidity (Correct answer)
- Always use a 1:1 ratio by weight
- Always use a 3:1 ratio (powder to water) regardless of brand
- Ratios do not matter as long as the paste is pliable
Correct answer: Follow package instructions, as ratios vary by brand and humidity
Gum paste powder ratios vary significantly by brand and are also affected by ambient humidity, making it essential to follow the manufacturer's specific instructions.
Question 4: Which piping tip produces a classic rope border on a cake?
- Star tip (e.g., Wilton 1M)
- Basketweave tip (e.g., Wilton 47)
- Round tip (e.g., Wilton 12)
- Rope/closed star tip used with a twisting motion (e.g., Wilton 6B) (Correct answer)
Correct answer: Rope/closed star tip used with a twisting motion (e.g., Wilton 6B)
A rope border is created using a large closed-star or rope tip with a twisting overlapping S-motion to produce the intertwined rope appearance.
Question 5: What does 'cold process' mean in the context of making sugar syrup for pulled or blown sugar?
- Cooling the sugar syrup rapidly on a marble slab before pulling (Correct answer)
- Dissolving sugar in cold water without heat to make a raw syrup
- Using isomalt instead of sucrose to lower the working temperature
- Refrigerating pulled sugar pieces before final assembly
Correct answer: Cooling the sugar syrup rapidly on a marble slab before pulling
In pulled/blown sugar work, the 'cold process' refers to rapidly cooling the cooked syrup on a cold marble or granite slab to achieve a workable, uniform temperature.
Question 6: A cake decorator wants to achieve a 'naked cake' look. Which technique best describes this style?
- A cake frosted entirely in white royal icing with no other decoration
- A cake with very thin, semi-transparent layers of frosting that allow the cake layers to show through (Correct answer)
- A cake with no filling between layers and only a top glaze
- A cake finished entirely with mirror glaze and no additional piping
Correct answer: A cake with very thin, semi-transparent layers of frosting that allow the cake layers to show through
A naked cake features minimal frosting — often just a thin scrape — leaving the cake layers and filling visible through the translucent coating.
Question 7: When assembling a gravity-defying cake (e.g., a floating tier), what internal structure is typically used?
- Extra layers of fondant to hold the tier in place
- A steel or food-safe threaded rod anchored through the base board and cake (Correct answer)
- Stacked dowels glued together with royal icing
- Freeze-dried cake pieces that are rigid enough to support themselves
Correct answer: A steel or food-safe threaded rod anchored through the base board and cake
Gravity-defying cakes rely on a rigid steel or food-safe threaded rod run through the entire structure and secured to the base board to bear the cantilever load.
