Unlock the perfect flavour pairings for red onion according to data science. Explore unique recipes and discover the hidden mathematics of flavour.
Pungent aroma and garlicy notes are at the forefront of red onion's flavour profile, but identifying its perfect partner requires exploring its subtle nuances. We must examine the complex interplay of notes within its bouquet, like sulfur, tomato, and hints of chamomile. We need to understand how these notes affect each other and which complementary flavors they harmonise with.
To map these harmonies, we analysed thousands of ingredients, breaking each one down across 150 flavour dimensions, identifying which notes complement and contrast. Our exploration reveals, for instance, how the meaty, roasted 2-methyl-3-furanthiol in chicken thigh can enrich red onion, and how whole chicken's gallinaceous notes forge a beautiful synergy with its pungent aroma.

How Flavonomics Works
We've pioneered a unique, data-driven approach to decode the intricate art of flavour pairing. Our goal is to move beyond intuition and uncover the science of why certain ingredients harmonise beautifully. This rigorous methodology allows us to provide you with insightful and reliable pairing recommendations.
Our analysis begins with over 50,000 carefully selected recipes from acclaimed chefs like Galton Blackiston, Marcello Tully, and Pierre Lambinon. This premium dataset ensures our model distils genuine culinary excellence and creativity.
Each ingredient from these recipes is deconstructed across 150 distinct flavour dimensions, creating a unique numerical "flavour fingerprint." This quantification allows us to apply advanced analytical methods to identify complex patterns between flavour notes.
We identify popular ingredient combinations that frequently appear in our recipe database. Regression analysis is then performed on these pairings to statistically validate and pinpoint truly harmonious flavours.
These insights drive our predictive model, which allows us to take any ingredient (e.g., Red onion), analyse its detailed flavour profile, and accurately reveal its complementary flavours and perfect ingredient partners.
