Chilli Sauce Costing works out what one bottle of your sauce costs: ingredients from The Pantry (what you paid, or a supermarket price: Pak'nSave first, then New World or Woolworths if Pak'nSave doesn't have it; alcohol from Whisky & More, then Liquorland) plus the bottle and cap. Home-grown chillies can be priced or left free.
