Preheat oven to 425 degrees F. Line a baking sheet with parchment paper.: The air warms quickly and you will smell a faint toasty scent as the oven reaches 425 degrees F . Lining the sheet with parchment prevents sticking and helps the underside of the dough brown evenly without burning. I always press the parchment flat so the dough lays smooth, which helps the wrapped dough bake uniformly. A common mistake is not verifying the oven temperature, which can leave the dough pale and doughy, so use an oven thermometer if you are unsure. Expect a gentle hum from the oven and a dry heat that crisps surfaces during baking.
Make 1/2 the recipe of our pizza dough for these mummy dogs.: Fresh dough should feel soft, slightly tacky, and elastic when you stretch it, and it will give off a faint, yeasty aroma. I mix, knead, and let the dough rest so the gluten relaxes, which makes it simple to roll into strips without snapping back. If the dough is too cold it will tear easily, so let it sit for a few minutes at room temperature after refrigeration. Overworking can make it tough, so stop kneading once it is smooth and slightly springy. You want a dough that bends and yields with a satisfying elasticity.
Once your pizza dough is made, roll pizza dough into a long rectangle.: As you roll the pizza dough , you should feel it spreading smoothly under the rolling pin and hear a soft whisper as the dough thins. Aim for an even thickness so the strips bake consistently, and dust the surface lightly if it sticks. If parts of the rectangle are noticeably thicker, the dough will take longer to cook there and the strip may remain doughy, so reroll those areas. The edges should be neat so strips will be uniform when cut.
With a pizza cutter, slice strips about 1/4" wide.: The sound of the pizza cutter gliding through the dough is crisp and satisfying, leaving clean edges that wrap easily. Strips about 1/4" wide make cute, mummy like bandages, and they bake to a golden crisp without overwhelming the hot dog. If strips are too wide they can obscure the sausage, and if they are too narrow they may burn quickly. Keep your cuts steady and even for the best visual effect.
Wrap the pieces of dough around each hot dog by stretching the dough slightly and letting it overlap and criss-cross. You don't need to completely cover the hot dog. Leave a gap at the top for the 'mummy eyes': When wrapping, you will feel the dough give as it stretches and the strip will cling when overlapped. The overlapping creates texture and little pockets that brown beautifully, releasing a toasty, yeasty scent. Intentionally leave a small gap at the top so the eyes appear, this gap also prevents the sausage from overheating in a sealed pocket. A common error is pulling too hard and tearing the strip, so gently stretch and overlap instead of yanking. The visual of criss crossed strips is part of the charm, and the contrast of darker browned dough against the exposed meaty tip is appealing.
Place the mummy hot dogs on your baking sheet and bake for 20 minutes. Remove from oven and let cool slightly.: As they bake for about 20 minutes, the kitchen will fill with the warm aroma of baked dough and savory meat. The dough should turn golden brown and feel firm to the touch when done, and the sausages will sizzle slightly at the exposed ends. Letting them cool slightly helps the dough set so the wraps do not unravel when handled. Avoid cutting into them immediately as hot steam can escape and make the interior soggy. A common pitfall is overbaking, which leads to a hard crust, so check for an even golden color rather than relying solely on time.
You can create the eyes a couple of different ways. The first is to squirt just a tiny bit of mustard for each eye. The second is to take a toothpick and place a tiny dollop of cream cheese for each eye and then a piece of chopped olive.: These finishing touches are where personality comes in, and you will notice the contrast of tangy mustard against the rich dough. Using a toothpick to dot tiny amounts of cream cheese gives a creamy base to anchor a chopped olive , which adds a salty pop. If you use straight mustard , squeeze gently to avoid large globs. One mistake is adding too large an eye, which can look disproportionate, so keep the dots small and precise. The tiny details make them playful and snackable.
Place ketchup in a small bowl. Squirt thin circle rings of mustard on top of the ketchup and then take a toothpick and drag it from the inside of the circles to the outside to create a spider web shape. Serve the mummy hot dogs with the spiderweb ketchup.: When you layer mustard rings on the ketchup surface, surface tension keeps them defined until you drag the toothpick, which creates the web pattern. The mixture will smell bright and tangy, and the visual adds drama to the platter. Keep your motions steady while dragging the toothpick so the lines remain clean. A common oversight is making the rings too thick, which ruins the web effect, so aim for thin, even lines. Place the mummies beside the bowl while slightly warm for the best contrast of textures and temperatures.
