The Chili Crisp That Vibrates at 50 Hz (We Verified the Neuroscience and the Sourcing)
Made the cut
Sichuan peppercorn contains a compound called hydroxy-alpha-sanshool. It does not activate pain receptors. It activates touch neurons.
Researchers at University College London measured the sensation and found that people perceive the tingle at approximately 50 Hz, the same vibration frequency detected by touch-sensitive nerve fibers in the skin.
Your lips vibrate. Not from heat. From a chemical that mimics physical movement where none exists.
We scored the Fly By Jing Sichuan Chili Crisp Trio at 8.50 on the SleekNova Scale. WOW scored 9 out of 10. Most recipients have never felt ma la. The Sichuan peppercorn tingle is not a hot sauce variation.
It is a categorically different sensory event.
What We Verified About Sourcing
Fly By Jing sources Tribute Pepper peppercorns from the Qingxi mountains, hand-harvested once a year. The heritage Erjingtiao chili peppers come from Guizhou province. All three sauces in the trio are crafted in Chengdu, Sichuan Province.
We confirmed these claims through the brand’s product page and About page, cross-referenced with editorial coverage from The Kitchn, Sporked, and Reviewed.
The brand bills itself as the first 100% all-natural Sichuan chili sauce. Vegan, no preservatives, no artificial flavors. B Corp certified. Founded in 2018 by Jing Gao, who launched with a Kickstarter campaign that became the most successful of any food brand to date.
What the Scores Mean
WOW scored 9 because the ma la tingle is genuinely unfamiliar to most people outside of Sichuan cuisine. Hydroxy-alpha-sanshool stimulates touch neurons instead of pain receptors.
For someone whose condiment shelf holds sriracha, gochujang, and three hot sauces, the trio introduces a sensation they have not encountered. That is the definition of discovery factor in our methodology.
GLOW scored 8 for bold Chinese typography on glass jars, a vibrant red-green-gold palette, and a gift box that photographs well.
MOMENT scored 8 because the three-jar format invites immediate exploration: the Original delivers the classic tingle, Chengdu Crunch adds fava beans and pumpkin seeds for texture, and Zhong Sauce pivots to sweet-tangy, inspired by a specific Chengdu street snack called Zhong Dumplings.
Three jars, three completely different reactions.
TRUST scored 9, driven by 4.9 stars across 3,944 brand-site reviews on Okendo with a 98% recommendation rate. Amazon shows 10,305 reviews for the Original alone. Sporked gave the Original a perfect 10/10. Jing Gao won the 2024 James Beard Foundation Media Award for Visuals. Editorial coverage spans NYT, Forbes, CNN, BBC, Esquire, and Food & Wine.
Final score: (8 × 0.25) + (9 × 0.35) + (8 × 0.25) + (9 × 0.15) = 8.50.
Why the Trio Format Matters for Gifting
A single jar of chili crisp is a condiment. Three jars with three different Sichuan profiles become a tasting experience.
The Original delivers the spicy-crispy-tingly balance. Chengdu Crunch rattles with fava beans, pumpkin seeds, and sesame. Zhong Sauce breaks the pattern entirely with sweetness and umami from a Chengdu street food tradition.
At $45 for three 6oz jars, the trio runs $15 per jar. Individual jars retail for $10 to $15 at Whole Foods, Target, and Walmart. The gift box arrives ready to hand over with no wrapping needed.
For anyone shopping for a friend who cooks or looking for a birthday gift that enters daily rotation, the trio removes the friction of choosing a single jar.
The Competitor Landscape
Lao Gan Ma popularized chili crisp and uses artificial flavoring with MSG. Momofuku Chili Crunch is made in the USA with domestic ingredients.
Fly By Jing sources heritage Erjingtiao peppers and Tribute Pepper Sichuan peppercorns from the Sichuan countryside and produces everything in Chengdu. No domestic chili oil replicates the ma la sensation from Tribute Pepper because the compound responsible, hydroxy-alpha-sanshool, requires Sichuan peppercorn varieties that are not grown domestically at the same grade.
Other brands sell heat-level variations. The Fly By Jing trio bundles three genuinely different Sichuan profiles in one gift box, from the Original’s tingle to the Chengdu Crunch’s texture to the Zhong Sauce’s sweetness.
One box, three discoveries.
Who This Trio Is For (and Who Should Skip It)
The trio works for anyone who puts hot sauce on everything but has never experienced the Sichuan peppercorn tingle. Home cooks who want restaurant-depth from a single spoonful on eggs. Ingredient-label readers who care that the Tribute Pepper is hand-harvested once a year in the Qingxi mountains.
Works across housewarmings, thank-you gifts, and holidays. $45 hits the generous-but-appropriate range for colleagues and someone who has everything.
Skip if: soy or sesame allergies (all three jars contain both), gluten sensitivity (Zhong contains wheat), preference for low-oil condiments, or if $45 feels steep next to $3 Lao Gan Ma.
