Inserting a round peg in a round hole should be easy. Writing about it and even visualizing it and minds veer in directions we would prefer to avoid, in this space. In any case, the idea of combining a doughnut and a hot dog has been on our mind and on our to-do list since we opened Curiosity Doughnuts. We finally made time to tinker with the idea. We use Zweigle's Pop Open hot dogs. We insert them into our doughnut and fry the two together for 2 minutes on each side at 375°F. The dog crisps and pops open. The doughnut cooks through and becomes crackling on the outside and steamy and tender inside. We served the dog with our smoked thousand island dressing. The doughnut dog was delicious. The sauce on the side was a full flavored accompaniment to the richness of the doughnut and dog. It was a pleasurable eating experience. And that is where the dilemma is. The doughnut dog, the combination of the two ingredients, is not better than the originals on their own. Cooking them together, while unique and visually disturbing, does not enhance the two. The doughnut dog is really damn delicious. But it falls short as a life changing experience. Back to the kitchen to tinker. It's not as simple as putting a round peg in a round hole.
