The addition of other ingredients is required to make an actual dish containing the relevant pairs. So it doesn't matter if A and B, B and C, and A and C all taste good together; if A, B, C, D, E, F and G together taste good, that's counterexample like the corned beef salad. But, the first point is talking about ingredients A, B and C, C and D, and A, B and D, where A is salt and B is cucumber; this is not a triad. Also, the recipes with A and B together would presumable contain A, B and P, Q and R; A, C, S, T and U; B, C, V, W and X; that is, each combination is used to make a dish that has other, ancillary ingredients.
