Hi Curry king,
Because of the different size of the various spices, some
people prefer to roast the different spices individually, mix
them together and then grind them together. Do not
roast too long. Basically heat till they become aromatic and
change colour SLIGHTLY ie do not over roast. The term
normally used is '' when the spices become one shade darker''
For traditional curries, this is the way to go!, especially your
Garam Masala. It is very quick and may be less expensive than
buying ready mixed. (Sure tastes better!) Unfortunately I
don't know how the restaurant/take away trade does it?
(If it was me with a restaurant/take away, I would probably
grind my own to save costs - it all adds up long term)
Respectfully,
Barry.
PS. Store in an airtight container IN THE DARK. All spices de-
teriorate in the light. If the container is dark, ok, else store in a
cupboard or other dark place. This may be obvious to us oldies
but not necessarily to the newbies.
