For the pickle: Place the carrots, daikon, lemongrass, garlic, lemon zest, rice wine vinegar, white wine vinegar, sugar, and 1 cup water in a medium saucepan. Set it over medium-low heat and gently simmer until the carrots and daikon are tender but still crunchy at the core, about 30 minutes. Remove and discard the garlic and lemongrass. Use a slotted spoon to remove the carrots and daikon from the pickling liquid, setting the liquid aside for another use.
For the Sriracha aioli: Add the sriracha, eggs, lemon juice, garlic, salt, and pepper to a blender and puree until smooth. With the blender running on medium-high speed, slowly add the olive oil in a slow and steady stream until the mayonnaise is emulsified. (The amount of oil you need may vary.)
For the banh mi: Position an oven rack to the upper-middle position and heat the broiler to high heat. Brush the cut sides of the brioche buns with butter, then place them buttered-side down on a griddle or in a nonstick skillet and cook over high heat until golden brown. Place a hot dog in each bottom bun half. Add a few cucumber and jalapeno slices, then spread with 2 tablespoons of sriracha aioli. Top with some pickled daikon and carrot and sprinkle with the chopped cilantro.
Steaming hot dogs is the preferred method since they retain their snap.
