Calculation Methodology
- Linear scaling: Most ingredients scale directly
- Non-linear items: Spices scale at 75% rate
- Time adjustment: +25% for doubled recipes
- Pan size: Scale by area not linear dimension
- Yeast/leavening: Special scaling formulas
Factors We Consider
Season to taste when doubling - spices don't scale linearly
Increase cooking time 25% when doubling, not 100%
Baking recipes scale poorly beyond 2x or 0.5x
Test scaled recipes before important events
