Perfect Pairings & Recipes for
Caramelised Onion

Top flavour pairings and caramelised onion recipes, revealed through the hidden methmatics of flavour.

Warm sweetness and molassesey notes are at the forefront of caramelised 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 toast, honey, and hints of dipropyl disulfide. 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 analysis reveals, for example, how tomato's glutamic tones enrich caramelised onion, and how kale's brassica notes create a surprising synergy with its warm sweetness.

An ingredient's flavour profile is determined by its core characteristics (e.g. maillard, nectarous, and herbal) enhanced by layers of subtle aroma notes (outer bars). When pairing ingredients, aim for a mix of core traits to build balance, and select complementary aroma notes to create harmony.

Unlocking Flavour Combinations

To understand exactly which flavours harmonise, we compiled a database of over 50,000 ingredient pairings commonly used in cooking. We then analysed these pairings, identifying the specific flavour notes that frequently appear together.

The Flavours That Harmonise With Caramel Notes

Our analysis shows that the flavour of caramel is strongly associated with the flavour of cabbage. This suggests we should look for ingredients with a cabbagy flavour, such as kale, when pairing with the caramel aroma accents of caramelised onion.

The recipe below provides inspiration for pairing caramelised onion with kale.

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., Caramelised onion), analyse its detailed flavour profile, and accurately reveal its complementary flavours and perfect ingredient partners.
