What changes

Properly salted pasta water is often preferred in blind tests at rates 20–40% higher than unsalted-water controls.

When this tends to work

  • Conditions similar to: Home and test-kitchen trials, plain tomato sauce, 2020–2025
  • You can measure Blind taste-test preference score reliably
  • The intervention is implemented consistently, not half-measured

When to be careful

  • Your audience or product differs materially from the cited context
  • Compliance costs or second-order effects outweigh the lift
  • Evidence label is study—treat wide ranges as planning bands, not promises

Practical takeaway

Use the cited range for prioritization and test design. Verify against your own data before scaling.
