A few of months ago, Waitrose were clearing out some curry spice kits ("Simply Cook" versions) at half price. Despite being a purist (I've got a masala dabba and I'm not afraid to use it) I was very pleasantly surprised with the effectiveness of these kits, so much so that I thought I'd try some of the "Spice Tailor" ones which I found less appealing and won't be repeating, although they are apparently popular.
The concept is an interesting one, selling small quantities of spice at a large markup, but the overall cost is low and convenience high, slashing preparation time and allowing you to make a good approximation of a real curry ultra fast.
Anyone use these? Any other recommendations? The "Bang" ones any good?
