I quite like liver - I wouldn't say its my favourite meat, but I'll happily eat it if its cooked properly. I rarely cook it though because my husband doesn't like it.
I do love a good chicken liver parfait or pate. I always make a pate around Christmas time but I've never tried to make a parfait.
Foie gras is a real treat - we've got one can left of the ones we brought back from France last year but we haven't decided yet when we're going to have it (it'll be either valentines day, our wedding anniversary or my birthday). Its funny that hubby actually likes it given his dislike of liver, but the texture and flavour is very different so I guess that explains it.
