Big Mac, Whopper, Eddie Rockets, Quarter pounder down the local chipper?? For me, the best are my ma's that she makes with fresh mincemeat, onions, cheddar cheese and some type of relish she buys in Tesco's. She mixes the onion through the mincemeat...pure quality.
The reason I'm bringing this up is that I read an article in FHM about how to make the worlds best burger.
Apart from my ma's, if I had to buy one, I suppose a Burger King whopper is the best, although I love those gherkins you get in McDonalds.....
