On special offer this evening in Intermarché: kilo bags of pork fat (yum!), ducks hearts (tightly vacuum-packed together in deep purple-red blood) and most disturbing of all, langue de boeuf. I mean, have you ever seen a cow's tongue? The tongues on sale in Intermarché are enormous, each curled around in a big fatty slab. I know that offal is fashionable and ethical (if you're going to kill an animal you should try and eat all of it et tout ca) and I know that some people probably have very delicious recipes for duck hearts and cow tongues, but never has pizza seemed so appealing.
