DiosaBellissima, hope you dont see this as a hijack - but in the interests of minimising ignorance and all that - and it’s not worth starting another thread - especially considering the last line of your OP.
Some translations:
Beetroot (US beet) - an ingredient found on hamburgers in Australia. Obtained sliced in a can. The beet is pickled in a sweet, vinegery solution, which is discarded. It is included in ‘hamburger with the lot’ in most Australian take-away shops and on the ever-popular ‘salad sandwiches’ obtained from sandwich shops. I mentioned this thread to my wife - she said that Mcdonalds now have a McOz burger with beetroot.
BBQ - I thought a BBQ was the same over here as everywhere else. It is plate or grill with a heat source underneath (usually gas these days) that you cook meat on outdoors. Prior to the 1990s, these used to be wood fired, brick or besa-block shrines to carnivouresness, which also served as rubbish incinerators or spider sanctories in the off-season. Now we have meals-on-wheels: a trolleys with hot-plate and gas cylinder attached.
Grill - to cook with infrared radiation. The food usually kept off the heat source by a series of parallel metal bars (a grill). Heat souce can be coals from wood or charcoal, but most commonly now is volcanic rock heated by gas. One can also grill underneath a heat source - such as metal mesh heated by gas. By gas I mean LPG, not petrol you put in cars.
In a BBQ, meat is cooked on both the hot-plate and grill. Most BBQs have a hot-plate and grill section. The grill is good for giving the rich, distinctive, polyaromatic hydrocarbon flavour. However the flat hot-plate is most commonly used. Reason you tilt the BBQ is to allow the fat that comes off the meat to drain away - usually to start a fire inside the BBQ, which is a good thing because it heats up the plate more than the pissweak gas does. Another reason to put the snags on first. These act a a fuel source for the steak and chops.
Sausages, onions, lamb chops and steak are the most commonly cooked things on a BBQ. Baby octopus, fish, shish kebabs and vegetables can also be found being cooked on BBQs across the coutry. Making hamburgers at a BBQ sounds like a lot of effort - not something I have ever seen done. Here all the meat and cooked onion is collected and served on a large plate together with a selection of large bowls of salads and bread rolls. The guests help them selves to the meat, salad, rolls and beer.
Steak is expensive here too now - I bought some for a BBQ at a mates place tomorrow at $22/kilo which is probably about US$16/kilo or one hours average wages.
