The perfect accompaniment for any barbecue - slather it on sausages and burgers.
Fry the onion and garlic in olive oil with the chilli, fennel seeds and sugar.
Add the soy sauce and ketchup and season with salt and pepper.
Bring to the boil and simmer for a few minutes to combine the flavours. Use as a dip or to coat spare ribs, chicken or sausages.
