Broth, fermentation and vegetables: building balance in Asian food

When flavour gains layers, bite and a little more direction

Balance in Asian cooking is often about layers: broth, fermentation, vegetables, acidity, heat, salt, sweetness and umami. The individual elements should not compete for attention, but give one another direction, depth and freshness. This article explains how broth can carry flavour, fermentation can create complexity, and vegetables can add bite and movement to a menu.

At Kromans in Copenhagen, the subject matters because Asian cooking quickly reveals whether you are seasoning properly. It is not enough for the dish to be hot or appear exotic. It needs to hold together. Small adjustments to acidity, salt, heat, texture and umami can transform the whole experience and make the difference between a heavy dish and a lively menu.

Asian balance is not one flavour, but an interplay

‘Asian food’ is an enormous term. So enormous it almost deserves a chair of its own. It therefore makes more sense to discuss specific flavour techniques: broth, fermentation and vegetables. These three elements can create balance in many Asian-inspired dishes without pretending to cover an entire continent on one plate.

Broth provides a foundation. It can be light, deep, aromatic, hot or mild, but it needs to carry the dish. In tom yum gung, the broth is not merely liquid. It is where acidity, heat, prawns and herbs meet. UNESCO describes tom yum gung as a traditional Thai prawn soup containing ingredients such as lemongrass, kaffir lime leaves, galangal and shallots, showing how much aroma matters to the character of a broth.

Fermentation creates complexity. Kimchi is a good example because it brings acidity, salt, spice, crisp vegetables and depth. UNESCO describes kimjang as a Korean tradition in which kimchi is made and shared as a community, showing that fermentation also has a social and cultural dimension.

Vegetables bring texture and freshness. Pak choi, green asparagus and watercress can keep a dish lively, particularly when meat, marinade or strong elements are also involved. The vegetables should not lie there like decoration with low self-esteem. They need to provide snap, bitterness, freshness or juice.

Pay particular attention to…

Broth needs sufficient depth to carry the rest of the dish.
Fermentation provides acidity and complexity, but needs balance.
Crisp vegetables matter when the menu also includes meat, heat and sweetness.
Umami should not become heavy without freshness.
Seasoning is essential because small adjustments alter the whole dish.

How to build balance in practice

An Asian-inspired menu works best when you think in contrasts. Broth against grilling. Fermentation against richness. Vegetables against heat. Coconut against spice. Acidity against sweetness. These are not random opposites. They are how the dish remains lively.

If a broth lacks acidity, it can feel flat. If it lacks salt, the aromatics can seem distant. If it lacks depth, strong chilli merely becomes sharp. This is why tom yum gung is such a useful teacher: it punishes inattention but rewards care.

Fermentation should not be used merely because it sounds fashionable. Kimchi works because it provides a specific counterpoint: acidity, crunch, chilli, salt and depth. It can make grilled or marinated meat feel fresher and more appetising. Too much, however, and it can take up all the space. Kimchi should play in the band, not steal the microphone all evening.

Vegetables are the third key. Pak choi, asparagus and watercress provide green freshness and texture. They need to be treated so they retain some life. Too much heat and they become sad. Too little seasoning and they become decorative. There is no point inviting vegetables if they are simply going to stand around watching.

At Kromans, this becomes tangible at the tables. You taste, adjust and feel how broth, fermentation and vegetables change the rhythm of the menu. The social setting genuinely helps because more senses are involved. Someone notices the acidity. Someone misses salt. Someone says the vegetables need more bite. Then the dish begins to improve.

In short: 5 things you need to know…

Broth is the foundation of many Asian dishes.
Fermentation provides acidity, salt and depth.
Crisp vegetables keep a menu fresh and lively.
Balance requires heat, acidity, sweetness, salt and umami to work together.
Tasting as you cook is the most important technique, even when the recipe appears reliable.
