me. MUST have Cheese - ideally processed plastic stuff but cheddar or swiss cheese will do i guess; onions: raw, grilled or fried (not onion rings in batter, or US 'crispy fried' though as these are dried onions, just use the real thing - all good; gherkins: also essential, preferably sliced, not a huge one dolloped awkwardly between the meat and the buns
; slices of beef tomato, iceberg lettuce, mayo, ketchup or burger relish, and mustard (I like strong English rather than American, but that or Djion are also fine...). And a strong bun that holds the lot together. I do like brioche style, althoygh that is a bit too sweet. Thats it. The idea of these flavours (such as the iceberg lettuce, and the simple, milky cheese), and holding the bacon allows the meat patty to have the starring role it deserves, so it really
is all about the burger.
