what does "desmechar" mean?
The question is "Qué significa desmechar"? which I think is related to the sentence in the grammar sheet "Revuelve bien y al final pon la carne desmechada con el resto de los ingredientes"
The dictionary on here doesn't recognize the word desmechar.

Sometimes when the dictionary fails, an internet search will pay off with a positive result. It seems 'carne desmechada' is 'shredded meat'.

Maybe it will help if I explain what we, Chileans and I think the rest of countries that speak Spanish, call carne "mechada"
To a big piece of meat you puncture/stab the meat with a knife making several holes all over the piece of meat and stick in garlic cloves, pieces of carrots etc...
So to me, it would mean that once the meat is done you take all of the "bits" in the meat out.
I might be wrong. 
As far as the dictionary side of things goes, my teacher recommended http://rae.es
The RAE dictionary is actually an online dictionary of Spanish words in Spanish, so it's not bilingual. However, it's really comprehensive, and I use it sometimes to check on meanings if I'm not sure a word actually means what I think it means. I generally use SpanishDict as my default though since it's a lot more work to use RAE.
By this point my answer is kind of redundant since it apparently means shredded in this context, but I just wanted to point you to what I found, especially since they're asking you specifically about the verb desmechar.
When I stuck it into RAE they said it was a Mexican colloquial thing and pointed me to "mesar" which means "Arrancar los cabellos o barbas con las manos." ("To tear out hairs or beards with the hands")
Another idea for translating tricky verbs is try to look at the structure of the verb and see if you can simplify it. Like, "des-" is generally the Spanish equivalent of "de-." Also, in this case, while "mechar" didn't yield anything except something about stuffing poultry ("unstuffed meat" didn't make any sense so I kept looking 
), the word mecha did.
Mecha apparently means a rather staggering variety of things: The one of primary interest in this situation though is "5. A lock of hair; a bundle of threads or fibers. (f)"
So if it can be a bundle of fibers, not just hairs, then it makes more sense for tearing apart meat, since it's like separating the fibers of the meat.
Guess I learn something new every day!
Hmmm I think desmechar means to de-hair something but it seems that carne desmechada or just 'mechada' means 'shredded meat'
