Preparing all the ingredients in advance is clearly my attempt to look professional but it does also save time at the cooking stage.
First I cooked spring onion, celery, red pepper and leek on a very low heat in a mix of butter and olive oil. This takes around 15 minutes for the vegetables to soften but not go brown.
A crushed clove of garlic was next and after a minute I added tomato puree, and a small amount of cumin, saffron and mild smoked paprika. I also put in a (optional) teaspoon of flour at this stage just to thicken it slightly.
For the stock I always use https://www.knorr.com/uk/knorr-products/stock-pots.html in this case it was the remains of a chicken pot and a fish pot. I see from their web site that there is a new kaffir lime and ginger which would be a great match for the salmon.
Bring to the boil and reduce the heat. Add the diced salmon and let it heat through being careful not to overcook.
Finish with a swirl of cream, or some yogurt or milk will be fine too and complete with chopped chives, parsley or thyme.
