I've never made it with the powder and roux though S & B curry tin has been in my pantry for ? years. I don't use it much as am more South East Asian curry fan. When there were no blocks in the house and kids jonesing I sent them across the road to major chain market to get a box which usually had S & B and Vermont (House). I think those "extra" lubricants were part of the appeal for them. Prior discussion
