1. food for its own sake, or
2. book for its own sake.
I like your idea of distilling down, and I think there's wisdom to it, and I do understand why you're using these. But at the same time, it's so easy to have someone deviate because of something unrelated to S/N. Both options could be interpreted via either process: food can be taken in on a near-purely Sensory basis, noting color and smell and shape and texture and name and components and quality and so on, but it can also easily be interpreted via iNtuition into fodder for evocation, distillation or recombination. Books, too, can be taken in focusing on the S qualities present, including illustrative detail, or through focusing on N implication. We commonly associate food - being a more pure manifestation of the concrete - more with Sensory intake and books - being composed of symbolic language - more with drawing out interpretation, but a person's non-MBTI preference for either could easily get in the way.
