Baked some choc oatmeal cookies( called crunchies in SA) today-. I was shopping yesterday- cat food was on sale- and decided not to buy more biscuits but to buy new cookie sheet instead- the old ones are rather scratched- fine for baking fish but not biscuits.
I figured the cost of a new cookie sheet at R30( $5) would pay for itself rather quickly as nice biscuits sell for about R6 a pack - 5 packets of biscuits or cookie sheet that should at least a year- about 52 packets of biscuits.
I allways keep some biscuits on hand for unexpected guests, must always be prepared. I find the idea of guests useful as a guide for cleaning the house- I do a walk through every day to make sure public areas are OK- if it's behind a door it can wait.
