Homemade Tomato Ketchup

We had burgers for tea last night - it was the perfect opportunity for me to experiment with ketchup recipes, one of which I found here. The end-product is very different to Heinz - but still completely delicious!

Ingredients:
2 cans of tinned tomatoes
1 medium brown onion
2 cloves of garlic
2tbsp oil
1tbsp tomato puree
Spices - I went with 1/2 tsp salt, 1tsp actual mustard (we were out of powder), 1tsp paprika, 1tsp mixed spice (if you have cloves, use those too), 1/2 tsp turmeric
100g brown sugar
About 70ml vinegar (I used cider vinegar)

Makes 2 medium-sized jam jars

Method:
1) Chop the onions whilst heating the oil in a large saucepan, then sautee for about 7 mins until soft and transparent.
2) Crush the garlic and add to the pan, cooking for 1 min
3) Stir in the tomato paste
4) Add all the spices, and stir thoroughly so they are evenly distributed
5) Add the sugar, vinegar and tinned tomatoes and stir
6) Heat gently for about 45 mins, until the amount of liquid has reduced
7) Use a blender (hand-held is best) to puree the sauce (NB: beware hot splashes of sauce - I wrapped a tea towel around my arm)
8) Transfer the sauce into clean jam jars - although it smells a lot like chutney when you're cooking, I doubt it would last as long on the shelf. But it's so tasty it wouldn't anyway!

Store in the fridge

Budget
Highly dependent on which spices you use, but the tomatoes, onion, garlic, sugar and vinegar add up to:
2 tins tomatoes = 75p (don't get the cheapest ones)
Onion = 10p
Garlic = 7p
Sugar = 25p
Vinegar = 8p
Total = £1.25
