Cooking on a campfire

Campfires can be used for cooking food by a number of techniques. Cooking food using a campfire can be tricky, and many campers prefer to use a portable stove instead. The techniques for cooking on a campfire are no different than those used for everyday cooking before the invention of stoves or where stoves are still not available. Individuals who are backpacking in an area that allows the gathering of firewood may decide to cook on a campfire to avoid the need to carry extra equipment; however, most campfire cooking is done in front-country campgrounds.

A pot hanging over the fire, although picturesque, may spill, and the rigging may be difficult to construct from found wood. Generally this is done with metal rigging, much of it identical to that used in home fireplaces before the invention of stoves. Two vertical iron bars with an iron cross-piece allow pots to be hung at various heights or over different temperatures of fire. Gridles, grills and skewers can also be hung over the fire. When working with wood, one may use two tripods, lashed with tripod lashings, but the rope will be liable to melt or burn. Dovetail joints are more secure, but difficult to carve.

Dutch ovens are specially designed for camping. The oven is placed in a bed of hot coals, often from a keyhole fire with additional coals placed on top of the lid, which usually has a raised rim to keep the coals from falling off. Dutch ovens are made of cast iron, and are not suitable for backpacking. Dutch ovens are also convenient for cooking dishes that take a long time. They are the not the only option for baking on a campout as devices for baking on portable stoves exist and clay ovens can be constructed at longer encampments.

Reflector ovens are placed on the ground next to the fire, and gather thermal radiation from it. Grills are somewhat simpler to use, and better at using convective heating, but they tend to make the food pick up flavors from the smoke. Grills over a campfire are used in the same many as ordinary charcoal barbeques. Grills that clamp over the food may be used for various tasks like warming food, grilling burgers or sausages or making toast. If the food is simply placed on the grill, it may catch fire. If the food is placed in a pot, the weight of the pot combined with the heat of the fire may cause the grill to bend permanently, and rest upon the coals, interrupting the flow of oxygen to the fire.

Possibly the simplest method of cooking over a campfire is to roast food on long skewers that can be held above the flames. This is a popular technique for cooking hot dogs or roasting marshmallows for making S'Mores. Another technique is to use pie irons -- a small iron mold with long handles, into which can be placed slices of bread with some form of filling -- which are placed over hot coals to cook.

Other simple methods include plank grilling where food is cooked on a wooded plank set vertically next to the fire and hot stone cooking where food is placed on a heated stone next to or even in the fire or sometimes hot stones are dropped into a pot.

Another technique is the baking of food in foil packets. Food is wrapped inside a durable packet of tin or aluminum foil, crimped to seal, and placed on or under hot coals. Baked potatoes are a common food cooked this way.

Measles Deaths Worldwide Drop By Nearly 40% Over Five Years
The World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) today announced that countries are on target to halve deaths from measles, a leading vaccine-preventable killer, by the end of this year. Global measles deaths have plummeted by 39%, from 873,000 in 1999 to an estimated 530,000 in 2003.

Origin Of 'Breathable'Atmosphere Half A Billion Years Ago Discovered
Geologists have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The study suggests that upheavals in the earth's crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world's oceans, spawned giant plankton blooms and sent a burst of oxygen into the atmosphere.

Antibiotic Rifampicin Shows Promise For Fighting Parkinson's Disease I
Researchers at the University of California, Santa Cruz, have shown that rifampicin, an antibiotic used to treat leprosy and tuberculosis, can prevent the formation of protein fibrils associated with the death of brain cells in people with Parkinson's disease. The drug also dissolved existing fibrils in laboratory tests.

Illinois Chemists Spray Their Way To Better Catalysts
Using a technique called ultrasonic spray pyrolysis, researchers at the University of Illinois at Urbana-Champaign have created an improved catalyst for removing smelly sulfur-containing compounds from gasoline and other fossil fuels. The improved catalyst is a form of molybdenum disulfide, most commonly recognized as the black lubricant used to grease automobiles and machinery.

Chemistry of Sex, Toothpaste, and Armpits

John Emsley bookI started a book on the chemistry of sex once…didn’t get very far, it was too distracting and working from home with my wife meant one thing led to another too often for us to knuckle down to the online research. TMI? Sorry.

Anyway, my good friend John Emsley who has been pounding the chemistry writing beat a lot longer even than me has just published another fascinating title on the chemistry and chemicals that underpins cosmetics, grooming, health, food, and, of course, sex.

In Better Looking, Better Living, Better Lovingtakes the novel tack of introducing each chapter with a mock news item about the next big thing in the various areas he covers, explaining how near-future chemistry used to develop the perfect toothpaste might develop and put dentists out of business, for instance, or a deodorant that could biochemically convert armpit odors into attractant pheromones. His news items are certainly tongue-in-cheek, but they do point to the very real ways in which chemistry impacts on almost every aspect of our lives.

Emsley tours plenty of the recent advances in chemistry, taking in the cosmetic factory, the pharmacy, the grooming salon, the diet clinic, the power plant, the domestic cleaning company, and the art gallery along the way. The tour is for anyone wanting to know more about the true impact of chemical products on our everyday lives, not just the nasties of tabloid scare-stories. Indeed, Emsley puts to rest several of the more ludicrous claims made for the effects of certain chemicals on our health and the environment.

He covers whether homeopathic medicines really work(you can probably guess his answer), the myth
of
date rapedrugs
the myth of date rape drugs, how the toxic chemical acrylamide gets into our food, and whether great
artists were affected by the poisonous pigments they used in their masterpieces.

With his informal, if deadpan, style, Emsley links his incredibly strong chemical knowledge to fun
situations, with a sneaky sideways glance or a roll of the eyes. Anyone suffering from chemophobia should read this. Anyone already singing with the chemical choir should read this. In fact, everyone should read this. Chemicals impact on all our lives, mostly in a positive way, rarely in a negative way (seriously). Emsley will help you understand the arguments on both sides, weigh up the risks and benefits, and make your own decisions about the chemistry of food, cosmetics, health, and, of course, sex.
