Hi Frank,
This is the recipe I use, and my daughter who is a Korma fanatic, will not buy a Korma from a restaurant anymore because she can't find one as good as this.
And before a certain person jumps on the bandwagon to try and gain brownie points on the forum, no it's not my recipe, but I cannot remember where I got it from, I think it might be CA's?? Anyway's give it a go and I hope you enjoy it

Serves 1-2
Ingredients:
300g skinless chicken breast (chopped into approximately 1 inch cubes)
60 ml veg oil
1tsp fresh garlic (pureed)
1 tsp turmeric powder
200ml curry base
6 tbsp coconut milk powder
2 tbsp sugar (or to taste)
0.5 tsp salt (or to taste)
100ml fresh single cream
milk (as required)
2tbsp almond meal (or cashew meal)
fresh chopped coriander - optional
Method:
Stir the coconut milk powder (and almond meal or cashew meal, if using), into the cream, to make a lump-free paste.
Heat the curry base to a gentle simmer
Heat the oil in a suitable pan (I use a cast iron wok) until almost smoking
Add the chicken and fry, for a couple of minutes, on high heat, with continuous stirring, until sealed (i.e. just white on the outside).
Add the garlic and turmeric and fry, for a minute or so, with continuous stirring (do not burn!)
Add a ladle of curry base and stir
Continue to add the curry base, a little at a time, stirring occasionally as the water evaporates and the sauce thickens.
Add the coconut/meal/cream paste and sugar and stir
Continue to simmer, on medium heat, stirring occasionally, until the oil begins to separate (5 to 10 minutes), maintain the sauce to the desired consistency by adding a little milk (or cream)
Add fresh coriander to taste (if using)
Serve
