There are some people who think that shop-bought are better. That Mr Kiplings has scores of baking experts finally crafting the ingredients and process to make the finest products that are humanly possible, well beyond the wit of all but the very best, and certainly above that of a mere amateur.
And then there are those that think the hygene practices of professional companies are flawless with all staff highly dedicated to following regulations, recommendations and best practice in order to uphold the name of the great company that they work for. And since home chefs haven't got the necessary qualifications in food hygene standards, and cake baking involves eggs, you really are taking your lives into your own hands by eating something that doesn't come off a supermarket shelf.
