These are the ingredients that I find essential to have (almost) permanently on standby in my kitchen cupboards. On average I estimate I spend £10 per month on adding to these ingredients. This works out approx 30p per day, and this is factored into the cost per individual serving in my recipes.
Where there is no amount next to an item in my recipe ingredients, I have classed this as a kitchen cupboard item, covered by the 30p daily average cost.
