Thanks for the welcome.
Made madras to go with the base in single portions, experimented with different spice quantities and got excellent results, much tastier than some curry houses I've been to!! Haven't found a good one in the town where I live which is a shame.
Been to morrisons again in readiness for darth's base which will be bubbling away later this evening, going to try it with no chilli powder to attempt different curries.
Has anyone else tried the base with curries other than madras? ;D
