Whilst I haven't been on here for sometime, I've been away in the kitchen experimenting on all sorts of things and my own base sauce which I now feel is ready to share with you. You will notice the large quantity of onions "2kg" which are sweated down in oil with freshly pureed garlic and ginger for 1 hour, before adding the other ingredients and water.
I've added pictures and a simple and easy methodology for people to try. Let me know what you think

Ingredients
2kg Onions, peeled and chopped into quarters
100g fresh garlic, pureed
50g fresh ginger, pureed
50g tomato puree
400g tin tomatoes
1 carrot
1 green pepper
1 star anise
2 inch stick of cinnamon
1 bay leaf
1 heaped teaspoon salt
25g fresh coriander chopped
4 heaped teaspoons spice mix (see below)
300ml rapeseed oil
2.5 litres water
Spice mix
4 tbsp Coriander powder
4 tbsp paprika
3 tbsp cumin powder
3 tbsp turmeric
1 tbsp garlic powder
1tbsp methi (fenugreek leaves rubbed into a fine powder)
2 tsp curry powder (I used Rajah Madras hot)
1 tsp ginger powder
1tsp chilli powder (Kashmiri Mirch)
0.5 tsp cardamom powder
0.5 tsp fenugreek powder
Method.
In a large pan add 300ml of oil, add the onion, garlic and ginger and bring to a high heat. When the mixture is hot and bubbling, reduce the heat to the lowest setting , cover and cook for 1 hour stirring periodically.
Add all the other ingredients except the spice mixture and freshly chopped coriander.
Add 2 litres of water and bring to the boil. Once boiling, reduce the heat to low, cover and simmer for 1 hour.
Remove the star anise, cinnamon stick and bay leaf and add the spice mixture, freshly chopped coriander and 500ml hot water.
Simmer on a low heat for 20 minutes, then remove from the heat and allow to cool.
Put the mixture into a blender and blend until smooth and a soup like consistency.
