According to research at UC-Davis, quite the opposite is true. The key finding: Our safety concern was that bacteria such as Escherichia coli O157:H7 and Salmonella, which might contaminate a work surface when raw meat was being prepared, ought not remain on the surface to contaminate other foods that might be eaten without further cooking. We soon ...

As well as personal experience from eating onions that were cut not on the same day. From the National Onion Association: Leftover Onion and Cut Onion Q: Are cut onions or leftover onions poisonous?

I love this question, because, until now, I never doubted lemon juice worked. I love this answer, because it surprised me even more than the question. Yes... and No! Lemon juice may make things better or worse. It depends on the avocado! Ascorbic acid works though. R. P. Bates, THE RETARDATION OF ENZYMATIC BROWNING IN AVOCADO PUREE AND GUACAMOLE, Proc. ...

No, searing doesn’t seal in the juices. Probably the only rigorous analysis of this has been done by Kenji López-Alt for Serious Eats. If searing does in fact "lock in juices," then we would expect that the steak which was first seared then roasted should retain more juices that the steak that was first roasted then seared. Unfortunately for old wives' ...

To say the explosion can't kill you seems a bit exaggerated. In this case, Elderly woman has leg horrifically severed after home pressure cooker exploded, a woman died after the explosion of a pressurecooker severed her leg (but not immediately!). Here is a second report of the same incident that is a lot more comprehensible: Miami Woman Dies After ...

The pictures are not fake. They are real photos of a phone baked into a cake, and then removed. However, the "Imagine this scenario. You drop your phone..." text is just imagination, not what actually occurred in making the photos. The photos are frames from the video iPhone 5S Baked In Cake - Will it Survive?. In the video, the narrator, TechRax, ...

In Germany, it's such a well-known advice to prick eggs before boiling that there is a kitchen tool which exists only to make Eier pieksen easier: the Eierpiekser. My mother had a cheap plastic one (ca. 1970), but it seems that you can pay 10€ or even more for the stainless steel version.

It's possible, but unlikely. It's possible Cakes cook from the outside in. If you are not careful you might pull out a cake cooked outside but raw inside. This happens when the oven is too hot. What to do if my cake seems ready from the outside (it's brown as it should be) however it's not done yet inside? [...] If you find that your cakes are ...

Yes, washing vegetables does remove some of the water soluble vitamins, specifically B-complex group, and vitamin C; however, in general, the health benefits of washing vegetables by avoiding pathogens as well as residual pesticides, herbicides, and other such residuals greatly outweighs the nutrient loss. With regards to the nutrient loss, vitamin B-12 ...

Yes. McDonald's state they they apply sugar to their fries. This bit below is from the McDonald's Australia website. Q: Do you add sugar to the fries? A: We know that you want beautiful, golden brown French fries. Potatoes already naturally contain sugars that, when cooked, can rise to the surface in places and result in unevenly coloured French ...

(I endorse Schmuddi's answer but I'll keep this one for the historical background it provides.) The advice goes back more than one hundred years to a 20 January 1899 North Dakota Agricultural College, Government Agricultural Experimental Station for North Dakota, Bulletin 35, Some Chemical Problems Investigated by Edwin Fremont Ladd. However, the advice ...

This is nothing but trickery. In this particular case, it appears that they have a liquid in there that has a much lower boiling point, is heavier than the oil, has the same appearance as the oil, and it is boiling to give the appearance that the oil is boiling. In this particular case, lemon juice is the common liquid used. Experiment – 22 Effect: ...

tl;dr While aluminum is toxic in large quantities, the risks from intake of low quantities are uncertain. However, as a precaution it is recommended to minimize intake. For that reason acidic or salty food should not come into contact with uncoated aluminum, such as foils or dishes. Also, aluminum content of cosmetics should be minimized. There is an ...

The origin of this story seems to be a 1958 Reader's Digest article, "Percy Spencer and His Itch to Know", written by Don Murray: One day a dozen years ago [Percy Spencer] was visiting a lab where magnetrons, the power tubes of radar sets, were being tested. Suddenly, he felt a peanut bar start to cook in his pocket. Other scientists had noticed this ...

Regarding the nutrients, you're better off in general consuming the whole fruit, not just the juice. I'll look at oranges and apples. You can use the links and do the math to figure the same thing out for the other items, I imagine. Orange vs Orange Juice One medium orange (about 130g) contains 1.2g protein, 3.1g fiber, 116% daily value (DV) of Vitamin C, ...

Washing vegetables before you cut them wouldn't remove any nutrients since the skin of the vegetable protects it, just like in rain outside etc. Leaving vegetables soaked in water for to long and the protecting layer would disolve and the water get inside the vegetable though. Cutting the vegetables and then soaking them in water could also very likely, ...

TL;DR It depends on the vegetable, and what other preparation method you're comparing it to. A study in the Nov 2003 issue of Journal of the Science of Food and Agriculture (Paywall--some key points explained here). From the abstract: High-pressure boiling, low-pressure boiling (conventional), steaming and microwaving were the four domestic cooking ...

Flame can travel up the stream, that is not news. There are many hospital admissions every year from people trying to add some meths (ethanol + methanol, "lighter fluid" in USA) direct from bottle to the BBQ to get it going properly The problem occurs more often if the bottle has a wide opening, then you get easy flame transfer up the stream and into bottle....

Yes and no, if you are making your own Sourdough bread then I would say no, as you have created the starter and the yeast is all natural. However if you are buying shop bought bread then one of the ingredients to extend the shelf life of the bread is L-cysteine. L-cysteine is/can be derived from human hair(mostly from barbers in china apparently), and ...

In my opinion it existed in the past and might still exist, but if so it is extremely difficult to find in a restaurant. According to this entry in Chinese Wikipedia: 三叫鼠,又名三吱儿,求小鼠肉嫩,故以蜜糖餵母鼠,故又叫蜜唧,广东菜名,最早的文字记载来自《清稗类钞》饮食类: 粤人食鼠 粤肴有所谓蜜唧烧烤者,鼠也。豢鼠生子,白毛长分许,浸蜜中。食时,主人斟酒,侍者分送,入口之际,尚唧唧作声。然非上宾,无此盛设也。其大者如猫,则干之以为脯。 Rough translation: San ...

I found this article from Liberty Mutual regarding a study one of their researches did on this subject entitled "Is a Sharper Knife a Safer Knife? Liberty Mutual Researchers Investigate" The study findings, published in Applied Ergonomics (Vol. 24, pp 375-382), indicated that blade sharpness did indeed have a significant impact on grip and cutting ...

This is a question that would be better handled by the experts at Seasoned Advice (I suspect it would be a duplicate.) Their food safety tag description is a fantastic resource that I commonly refer to, correcting a number of myths and misconceptions. From there, we can see the answer to this question is not a simple "yes or no" - heating them once to a ...

Yes it is true that some fruits such as raspberries and vegetables such as spinach in supermarkets taste different, when compared to local farms and farmers markets since most varieties of fruits and vegetables found in supermarkets are chosen for yield, growth rate, and ability to withstand long-distance transport rather than taste. Fruit and vegetable ...

Alcohol chains are highly volatile and the resulting vapors are detectable by the human olfactory sense as odor.

Probably not this link explains the source of bitterness and how it is distributed in a cucumber: A natural organic compound called cucurbitacin is the culprit, according to Oregon State University vegetable breeder Jim Myers. The bitter compound is likely to be more concentrated in the stem end than in the blossom end of the cucumber. It is also ...

It seems likely to be true. In particular, Starboard Value made the claim as part of an extended, savage, and heavily reported critique of the then-management of the chain, where the "no salting" bit featured heavily in the reportage. The attack was clearly and openly being made as part of a takeover attempt. (https://www.sec.gov/Archives/edgar/data/...
