What changes
Browning tomato paste before deglazing is commonly associated with 18–35% higher umami ratings versus raw paste addition.
When this tends to work
- Conditions similar to: Tomato-based pasta sauces, home cooks, blind panels
- You can measure
Umami intensity rating in blind testsreliably - 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.
