Ordinary potatoes in E.A. are sweet potatoes = "viazi". European potatoes are "viazi vya kizungu". So I would translate "viazi vitamu" as delicious sweet potatoes. There are also other varieties of potatoes of which "kirehani" is one.
should it not be translated: I have cooked them sweet potatoes-meaning I have cooked sweet potatoes for them? I have cooked the sweet potatoes could be translated:nimepika viazi vitamu- or am I wrong?
Side comment here: I thought sweet potatoes were the same things as yams... so via vikuu... Are they different in Africa? Is my local grocer just being lazy?!?!
