orangeyness

O: orange juice concentrate in the first container / W: water in the first container / O′: orange juice concentrate in the second container / W′: water in the second container / The most natural ratios to be considered are O/W and O′/W′, O/O′ or O′/O and W/W′ or W′/W, O/B and O′/B′, W/B′ and W′/B′. Because differences rather than quotients also can be used under certain conditions, there are many ways of arriving at the right decision about the relative “orangeyness” of beverages B and B′.

Take an orange in your hand. Hold its golden goodness, feel the texture of its skin, the form of its roundness. Smell the tart orangeyness of the rind as you peel it, slowly and with awareness.
