2 questions about lamb broth and chard...

The questions aren't related to eachother...just wondering.


How long to simmer the lamb bones for broth - 48hrs or is 24 sufficient?


In trying to preserve the most amount of nutrients, I've been lightly sauteing the chard in some olive oil, thinking that it's not cooking long so it would keep the "good" stuff in - did I just make that up in my head?

What is the best way to preserve the nutrients/vitamins when cooking things like spinach, chard, kale etc.?

Well I simmered the broth for a little over 48 hrs ( I had about 4 racks of lamb bones in), had to add water 1/2 way through. It didn't gel, but did get thicker - does that sound about right?

It's not as yummy as the chicken broth I find..
