So tonight I finally made the first curry using this base. I sieved the base thoroughly, getting a great deal of detritus out, and then made a 1-portion Chicken Madras :
9 pieces of pre-cooked chicken, marinaded as for the Malabar Chicken Curry that was the start of all this and then lightly pre-cooked in oil, a little base, Kashmiri Masala paste and g/g paste. The chicken was most definitely /not/ fully cooked at the end of this stage. After pre-cooking, the chicken remained in the 'fridge at around 4oC for several days. Tonight I gently fried some g/paste in oil, then added the spices (2 teaspoons Bolsts Hot Madras Curry Powder, 1 teaspoon Bassar Curry Masala, 1 teaspoon Kashmiri Mirch, 1 teaspoon ground cumin, 2/3 teaspoon ground fenugreek, 1/3 teaspoon ground coriander -- all measures rounded), stirred well at about 1/3 power, quenched with 1 teaspoon tomato puree diluted with 2 teaspoons hot water, continued to fry then added one ladle base. When everything had thickened I added the chicken, made sure it was thoroughly coated, then added a second ladle of base. When that too had thickened I added the third and final ladle of base, waited for the oil to come out, then removed the chicken to rest under cling film while I reduced the base to my desired consistency.
The end result was excellent : the chicken was moist, juicy, tender and full of flavour, and the sauce was full-flavoured, rich and complex. Definitely one of my better curries, though with so many variables it would be hard to identify the key factors. Did marinading the raw chicken in lemon juice and spices contribute to the tenderness, or was this more to do with removing it to rest before the final reduction ? Certainly I would think that the more complex base added additional layers of flavour.
