Neil D, you use coffee as a seasoning? I have been tempted to try it does it give the food a slightly bitter taste? I have tried adding plain chocolate to chilli which is really nice and gives a richness to the colour too. For my spagetti sauce I add a dessert spoonful of vinegar and a teaspoonful of sugar, smoked paprika and a small amount of cayenne again for the colour. As a rule I stick to mixed herbs it's easier I haven't the patience to stand there milling through all the herbs. I use the light soy sauce in lots of things not just in oriental cooking. The slight saltiness is all I need in stews and casseroles or omelettes.
