Menu Development and Cost Controls
From Concept to Contribution Margin
Menu questions test whether you can connect culinary decisions to financial outcomes. Understand menu engineering using popularity (sales mix) and profitability (contribution margin) to classify items as stars, plowhorses, puzzles, and dogs-and know the standard responses to each. A plowhorse is popular but low-margin; raising price risks volume, so rework cost or portion instead. A puzzle is profitable but unpopular; reposition or rename it rather than cutting it outright.
Cost control starts with the standardized recipe: exact ingredients, yields, portion sizes, and plating. From there you build plate cost, then food cost percentage (plate cost ÷ selling price). Know how to calculate a selling price from a target food cost percentage, and how to adjust when yield or trim changes the true cost. Menu mix, sales forecasting, and the distinction between food cost and prime cost (food plus labor) are frequent topics. Beverage and labor cost percentages follow the same logic.
Traps to Watch
- Confusing markup with margin: a 25% food cost is not a 25% markup on cost.
- Using as-purchased cost when the recipe calls for edible-portion quantities.
- Forgetting that contribution margin is price minus variable cost, not profit.
- Treating a dog as automatically removable; sometimes it supports a guest need.
- Ignoring waste and spoilage when computing theoretical versus actual food cost.
Rule of Thumb
Selling price = plate cost ÷ target food cost percentage. Plate cost $4.20 at a 28% target = $15.00. To find food cost percentage from a price, divide: $4.20 ÷ $15.00 = 28%. Check which direction the question is asking before you compute.
