Sweet Braised Yams

I've been trying to incorporate some new sides in with our meals and when I saw these on My Fabulous Recipes I thought they looked great. I thought they were really good with a fun new flavor and a great change of pace from green beans and broccoli all the time. Preston really, really loved them...a great little baby food too :-)!

1 large yam, peeled and diced into bite sized chunks (I used a sweet potato...is there a difference?)
1 tablespoon olive oil
3 cloves garlic, finely chopped
1 1/2 inch piece of fresh ginger, grated or finely chopped
1 tablespoon brown sugar
1/2 cup chicken broth/stock
1/2 teaspoon fish sauce (optional) (I didn't use)
1 tablespoon lime juice
1/2 teaspoon crushed red pepper (optional) (I put a couple dashes)

-Heat the oil in a large frying pan, add the garlic and ginger and cook for 3 minutes over medium heat, stirring regularly.
-Add the yam pieces, sprinkle with sugar. Cook for 8-10 minutes, turning the pieces regularly until the yam is golden and just tender. (mine took more like 12-15 minutes)
-Add the chicken stock/broth and fish sauce, bring to the boil and cook, turning the yam over regularly, until all the liquid has evaporated.
-Sprinkle with lime juice and crushed rd pepper, season to taste with salt and pepper. Serve.
