Char as Flavour: Deliberate Blackening

Ottolenghi Flavour by Yotam Ottolenghi and Ixta Belfrage pushed beyond the vegetable-as-side-dish philosophy of Plenty into vegetables as the primary carrier of intense, complex flavour. The book's most significant technical contribution is the rehabilitation of char — deliberate blackening of vegetables beyond what Western cooking considers acceptable — as a flavour development technique rather than a mistake to be avoided.

The deliberate burning of the exterior of vegetables (onions, peppers, aubergine, corn, leeks) to produce a layer of bitter, smoky, complex char compounds that transform the flavour of the entire vegetable — the charred exterior flavouring the soft interior through contact during cooking.

Charred vegetables provide bitter, smoky complexity that no other cooking method produces. The char creates a flavour contrast within the same vegetable — the blackened exterior against the sweet, soft interior. This contrast is the dish. Without the char, the vegetable is merely roasted; with it, it becomes something categorically more interesting.
