The potato paradox
-
50lbs. 1lb == 1% of 100lb, and 2% == 50lbs So as not to give the game away! (hilight to reveal)

I dont get it. Should be 99.0001 lbs or some such.
OK, so 100ib of potatoes, 99% water. That means that 1% is not water, and that weighs 1lb. If you reduce the water content to 98%, that doesn't affect the non-water part, so 1lb of the potatoes is now 2% of the total. If 2% of the weight is 1lb, then the total weight is now 50lb. For 97% you get 33.3lb, 96% gives 25lb, and so on.

Forgive me for being thick but I cannot get my head round that. In 100lb there is 1lb of starch and 99 lbs of water (yes?). So if you lose 1% of the water, isn't that just 1lb less than before?

No googling, ok.
Ok, but than please ask it for 45.359237 kg ;P :-D
It does not solve my Problem, but it answers my question
OK - the new weight is 22.679618kg.

It's simple when you see it! :laugh: If I recall correctly, I scratched my head a fair amount the first time I saw this one.

You have 100 lb of "mathematical" potatoes, which are 99 percent water by weight. You let them dehydrate until they're 98 percent water. How much do they weigh now? No googling, ok.

That's more lettuce than potato. A potato will clock in at roughly 75% water (just a tad more than a human). Still a nice example where math beats intuition :thumbsup:

"To 98%" of what is the question. The original weight or the final weight. That wasnt specified. :)

That's pretty clear!

These are 'mathematical' potatoes. :) But feel free to substitute with jellyfish if you want to.

Could as well have chosen a mathematical ball of lead with 99% water-content. --edit It is misleading, since we have some "experience" with potatoes not shrinking 50% when they lay in the basement.

That's because they start out at 80% water, not 99%. And because nobody regularly checks their spuds for water content... :laugh:

I keep potatoes in a dark and cool closet. After 3 months, they may have lost "some" weight, but not the same amount as your "mathematical" potatoes. Non-mathematical potatoes do not loose water in a mathematical linear way.

Or as quickly - unless you use the fridge / freezer as a dehydration device, as you do for Triple-Cooked Chips, where reducing the volume of the chips before the final frying probably does approach 50%

In which case you extracted more than 1% of liquid. This was also not about volume; are you sure the shrinking is due to the loss of water? Or could it just be a reaction of those sticks to sudden cold when taking out of the oil? :)

Nope: you cut 'em, you simmer them until soft, then cool and into the fridge for 4 or 5 hours. When they come out, they are already smaller as the fridge has reduced the water content. Low temperature fry - 130C - cool, and back in the fridge for another 4 to 5 hours. When they come out, they are significantly smaller than they started! Then the high temp fry - 190C - drain and serve. Damn good chips - but quite a palaver (especially making enough room in the damn fridge).

So, you let them dry in your fridge and obsorb all the nice smells in there? :D

Which isn't very surprising after having been cooked, cooled, brought to cook in oil and cool again. Fact remains that it is not a mathematical potato, and that you removed more than 1% of liquid. As you probably know, lettuce IS mostly water, moreso than potatoes. Freeze your lettuce for an hour or four, then defrost. You'll find that those non-mathematical lettuce has lost more than just half of its water.
