Well, lets say you are cooking, lets say you are about to taste the flavour of the new preparation someone possibly your grandmother in Spanish will say something like: “Esta comida sabe a rosas”, this food tastes like roses. So we can use it in the context of  food preparations is one thing, but in the field of knowledge is another story. He knows the thruth will be like ” el sabe la verdad”, so basically in another context the meaning is completely different. Hope it helps!
