Preheat oven to 350°F.
Using a fork, poke a few holes into each potato. Rub the potato with olive oil and salt and place on a baking sheet. Bake the potatoes for about an hour until tender.
Peel the potatoes and run them through a potato ricer into a large bowl.
Add the crab, cream cheese, sour cream, scallions, jalapenos, and soy sauce. Mix to combine, breaking up the cream cheese and making sure everything is well incorporated. Taste and add salt or more soy sauce if needed.
Add a splash of water to the egg in a small bowl and whisk to form an egg wash.
Place a wonton wrapper on a working surface. brush the egg wash onto 2 touching sides of the wonton wrapper. Add a heaping tablespoon of the potato mixture to the center of the wonton wrapper. Fold the dry edges across to the egg-washed edge and press to seal in a triangle shape.
Repeat with the remaining wonton wrappers.
Pour the oil into a frying pan and preheat over medium-high heat.
Add half the rangoons to the oil and cook on each side for about 3 minutes to brown. Remove from heat and allow to cool on a rack or paper towel. Repeat with the remaining rangoons, adding a little more oil to the pan if needed
Meanwhile, mix the soy sauce, sesame oil, sriracha, honey, chili peppers, scallions, and sesame seeds in a bowl.
Serve the rangoons with the sauce on the side.
