How about some scalloped potatoes
or hash browns or you could use some for mashed potatoes.
Heh, not going to happen with the beautifully shaped tournet cuts.
Perhaps you should use the tournet shapes in something where your handy-work will not go unoticed like in a potato salad (not smothered in mayonnaise/cream/sour cream mind you) with perhaps some rocket, feta and walnuts dressed in an ev-oo and lemon juice dressing (or maybe a salad of some watercress, avocado and some optional pinenuts/walnuts).
Or perhaps in soup or stew where the shape will not go unnoticed (best of course in a simple clear broth or consomme...but would potato work well, you generally do not need potato used as a garnish in a broth).
