FAQ
How do I scale from 4 servings to 6?
Multiply each amount by 6÷4 = 1.5. Two cups becomes three cups.
Do spices scale linearly?
Salt, yeast, and hot spices sometimes need a lighter touch when scaling far up. Taste as you go.
What about pan size?
Volume scales with servings, but bake time depends on depth and pan material. Check early.
Can I scale baker's percents?
Yes. Keep percents fixed and change flour weight, or use the Baker's Percentage tool.
