I don't make make curries from scratch any more, mainly because of the wife complaining of the aroma left in the house after boiling large quantities of onions and frying the different spices etc. (funnily enough, curry powder was never an ingredient used that often).
These days I either purchase a takeaway or buy them ready made.
The day before yesterday I purchased the Sharwood one at ASDA and the one on the right from Aldi.
