Preserves
Onion and Chilli Marmalade
This onion and chilli marmalade is a rich, sweet, and gently spiced preserve that turns a simple set of ingredients into something truly special. With a mix of red and brown onions cooked slowly until soft and caramelised, this recipe creates a deep, mellow base that carries layers of flavour. Soft brown sugar adds warmth and richness, while a splash of port brings a round fruity note that sets this marmalade apart from more traditional versions. The cider and balsamic vinegars balance the sweetness with a bright, tangy lift, and the combination of mixed herbs and crushed chilli flakes gives the finished marmalade a subtle aromatic edge along with a pleasant touch of heat.
