Why every answer is cited

Most cooking advice online repeats other cooking advice. Tracing it back to a verifiable source — USDA on safe internal temperatures, NCHFP on canning, López-Alt on technique, Cook's Illustrated on ratios — takes hours. AskedWell does that work once, links the source on every answer, and shows the tier (peer-reviewed · editorial reference · named practitioner) so you can calibrate trust at a glance.
