In a medium bowl, stir together the flour, baking powder and salt. Rub in 28 grams of butter. Stir in the hot water until you have a soft dough. Turn it out onto the countertop and knead for a few minutes, until it’s smooth. Return it to the bowl, cover with a towel and set aside for 30 minutes.
Using sharp scissors, snip the chive flower blossoms into individual petals. Place in a small bowl. Using scissors or knife, finely slice chives into bowl with blossoms. Mix and set aside.
Divide the dough into four pieces and roll each into a rectangle (it can be oval-ish) as thin as you can – about 7x10 inches, with a long side facing you. Brush with the melted butter.
Starting at a long side, roll up tightly into a long roll, and then shape it into a coil. Repeat with the remaining 3 pieces of dough and let them rest for about five minutes.
Flatten each coil, gently with your hand, then re-roll into a 7x10 inch rectangle/oval for the second time.
Brush with another layer of melted butter and sprinkle with 1/4 teaspoon salt, 1/4 of the chives and chive blossom mixture and 1/4 of the toasted sesame seeds and roll up tightly into a long roll, and then shape it into a coil. Flatten coil gently, with your palm and re-roll into a 7-inch disk, about 1/4 inch thick. Repeat with remaining dough balls.
In a small bowl, whisk together sauce ingredients and set aside at room temperature.
Drizzle 1 tablespoon vegetable oil into in an 8-inch nonstick pan and heat over medium-high heat. Carefully slip pancake into hot oil. Cook, shaking pan gently, until first side is an even golden brown (about 2 minutes). Carefully flip with tongs and continue to cook, shaking pan gently, until second side is an even golden brown (about 2 minutes longer). Transfer to a paper towel-lined plate to drain. Season with salt and cut into 6 wedges. Repeat with remaining 3 pancakes. Drizzle with hot honey, if using, and serve immediately with dipping sauce.
