What's the best way to test new flavors before a full product launch?

For tight budgets, online panels through tools like Respondent.io or even targeted Facebook groups can get you solid directional feedback fast — aim for 50-100 respondents per flavor. That said, for snacks specifically, I'd pair that with a small in-person session (even 10-15 people) since texture and smell don't translate online. The combo usually catches blind spots that surveys miss.
