Heat oil in a large shallow pan. Throw in onions and cook for 10 mins, or until soft. Tip in the garlic and ginger, then cook for a further 2 mins, watching the garlic doesn’t burn. Stir in curry paste and cook for another min.
Now pour in 1 litre of cold water, the tomatoes and 1 tsp salt. Give it a good stir and bring to the boil. Cook the sauce over a high heat for about 10 mins, or until the liquid has reduced by a third. Will keep for 1 week in the fridge or freeze for up to 2 months.
