If you want a different texture for the sweet potatoes than the mashed potatoes, you
can bake them just like you would a baked potato. Or even cook them in the microwave. They are delicious served with butter, salt, and pepper, just like a baked potato. They are only 28 cents a pound here right now, so I bought about 10 lbs last week.
We are talking the orange variety, right? Technically, I think, "yams" are the large, whitish-yellowy ones. But then when I was researching this for my cookbook, I read that Louisianna trademarked their sweet potatoes as yams. I don't think that the white yams are widely available overseas, though, so we are probably talking about the same (orange-fleshed) ones!
