I spoke again with the ex restaurant chef, who supplied the curry gravy recipe at
https://curry-recipes.co.uk/curry/index.php?topic=3.0He was very pleased that my cooking was working out well at home.
When I ran through the recipe again, he said there was something missing.
He had difficulty pronouncing it and I had to bring him samples to identify.
It was thyme.
Now I wouldn't get too excited about this (although I have not tried it yet)
Because a lot of us have tried Bruce Edwards Curry House Cookery recipes.
He uses Ajwain Seeds (lovage seeds) and this has written on the pack
"aromatic ajwain seeds have a strong pungent flavour similar to thyme".
They are packed by Natco and sold in Asian shops, so I have no doubt they are used in indian cooking.
But the chef said I should be adding in 1 teaspoon of thyme (after I have ground it) along with the tomatoes.
He also confirmed the addition of chicken jelly, to the curry gravy, when it was reheated at the start of the evening.
I discussed the missing taste we have all talked of.
He replied that he told me everything, and had no idea what it could be.
I am 100% sure this is true.
When he used to cook, nearly all the flavour came from the curry gravy.
Pre cooked vegetables, chicken and lamb were all boiled in water, salt and turmeric.
Some meals were simply heated curry gravy with precooked ingredients added.
I don't suppose that all chefs have the same recipes but this is the truth from this one.
So we have from him
1 the full curry gravy recipe
2 precook instructions
3 chicken jelly recipe instructions
Everything else is down to experience.
We could always do with more "seen" recipes though.
I still want that.
