Essential Ingredient Guide

  • Cheerio‑style cereal: Look for the toasted, slightly salty version; it adds the signature crunch.
  • Sea salt (optional): A pinch enhances the nutty flavor and balances the honey’s sweetness.
  • Lemon zest (optional): A dash of zest brings a fresh brightness that lifts the bar’s overall profile.

  • Serving Timing:
