Combine all ingredients for the braising liquid in a large pot, stirring to partially break up the sugar. Add the wings and try to submerge them as much as possible under the surface of the liquid.
Heat until the liquid starts to boil, then turn the heat down to medium-low. Put a lid on the pot and cook.
After 15 minutes, check the temperature of a few wings with your Thermapen ONE. If they've reached a temperature over 165°F (74°C), you can take them out, but they can go up to 203°F (95°C). If they have not gotten there yet, keep cooking.
Once the wings are temping high enough, remove them from the braising liquid and place on a cooling rack set in a baking sheet. Place in the refrigerator to cool and dry.
Make the sauce:
Strain the braising liquid into a wide saucepan or deep skillet. Add the pepper jelly and apple cider vinegar and bring to a boil.
Continue to boil and reduce the sauce until it is sticky enough to leave a little track in the pan as you drag a silicone spatula across the bottom and coat the back of a spoon nicely. You should have 1.5–2 cups.
Fry the wings:
Fill a deep, heavy Dutch oven or other pot halfway with high-smoke point oil like corn or peanut.
Attach a ChefAlarm probe to the pot and set the high-temp alarm for 375°F (191°C) and the low-temp alarm at 350°F (177°C). Heat the oil.
When you reach frying temperature, place 4–8 wings in the oil and cook until the skin crisps and the wings turn a beautiful lacquered brown, about a minute.
Bring the oil back up to heat before cooking more wings. Repeat until all the wings have been cooked.
As each batch of wings emerges from the fryer, put them in a large bowl for saucing, add the sauce, and toss to coat.
Garnish with sliced serranos, chopped cilantro, sliced scallions, and sesame seeds.
