Pigs liver has the best flavour and I love to make a casserole in my slow cooker with lambs kidneys. Lamb's liver has no flavour and calve's liver is about 10 times the price of pig's liver
start by extracting mikey's liver and season it....talbot
Hot frying pan, splash of oil, no cognac for the sauce as there is plenty in the liver.... sear for no more than thirty secs a side, add a dollop of Dijon and cream and voila.....
Lamb or calf liver are best. There are several ways of cooking this, but I always use the Hairy Bikers' recipe, it always gives a good result and you can just google it. As a variation I do liver risotto occasionally, also v. good.
