*Eeky Alert*
See these frogs legs.....
Why does sprinkling them with salt make them twitch ?

Be fair sheepy, if I were to garnish your legs with a little mint sauce, it might well have a similar effect.
Being a bit of a numpty, I don't really know, but I think it could be some sort of electrostatic effect caused by water in the tissue being drawn out by the salt.

Salt, or NaCl, contains Sodium, which is required to generate an action potential in the nerves (motor nerves in this case). I'm guessing it has something to do with activating this action potential

It supposedly works like this:
The nerve signal, or action potential, is a coordinated movement of sodium and potassium ions across the nerve cell membrane. Here’s how it works:
1. As we discussed, the inside of the cell is slightly negatively charged (resting membrane potential of -70 to -80 mV).
2. A disturbance (mechanical, electrical, or sometimes chemical) causes a few sodium channels in a small portion of the membrane to open.
3. Sodium ions enter the cell through the open sodium channels. The positive charge that they carry makes the inside of the cell slightly less negative (depolarizes the cell).
4. When the depolarization reaches a certain threshold value, many more sodium channels in that area open. More sodium flows in and triggers an action potential. The inflow of sodium ions reverses the membrane potential in that area (making it positive inside and negative outside — the electrical potential goes to about +40 mV inside)

Thanks all for your replies !...very helpful indeed !....I wonder if this is a specific phenomena attributed to frogs legs cos I've never seen it happen on a chicken leg !....I suppose ' freshness' may have something to do with it !

Your frogs legs are obviously twitching in excitement about being on the menu.

I've...erhm...never eaten frogs legs !.......I know everybody says that when they try new things that the thing they are tasting always seems to taste like chicken..but I do believe that frogs legs do in fact taste like chicken....or is that Rabbit ?...oh...I dunno !! [:-\]
...erhmm...has anyone actually eaten frogs legs ?...what are they like ?
-
Yes, I have eaten them. They are quite good. Thanks for comments. Joe L. Ogan

Thanks Joe....can you convey what they taste like ?...the texture ?....I suppose you had them with garlic and butter perhaps ?

Frog legs have a rather unique taste. It is somewhat like chicken or rabbot or somewhat like fish. I find it a little difficult to describe it exactly because it is different. Why don't yopu get some and try them. You will like it. Thanks for comments. Joe L. Ogan

For me I will have to counteract the ' yuk' factor in my head first !...I need someone to surreptitiously introduce the meat into a meal and then tell me after that I'd just eaten them !

Well, the first time I ate frogs, they didn't taste like chickens. They were spicy. However, when I tried to eat fried frogs, they did taste like fried chickens. (I can assure you those are frogs, not toads)

Being from an Italian family and being brought up to eat anything I would love to try them but I have heard they are produced in an inhumane manner so would be reluctant to order them
