The seeming tide of luridly coloured cakes that are demonstrations of crafting ability rather than baking sills and barely look edible upsets me.
I can accept a hedgehog shaped birthday cake with chocolate fingers for spikes or fork-combed icing to make it look spikey, for example, but bright green/blue/red icing just doesn't look tasty and doesn't make me want to eat it.
Cake should look yummy and edible.
And don't get me started on "cupcakes" with immense swirls of pastel buttercream icing (though pastel colours are marginally more edible-looking) - sickly!
Grumble grumble.
