1. 1 For the Annatto Oil: In a small saucepan, heat oil and annatto seeds over medium-low heat, stirring and swirling pan occasionally, until warmed through and shimmering, about 5 minutes. Remove from heat and let oil cool for 15 minutes. Using a fine-mesh strainer, strain oil into a bowl or jar; discard seeds and set oil aside until ready to use.
2. 2 For the Pork Paste : In a food processor, process ground pork until it forms a smooth paste, about 1 minute. Transfer to a plastic wrap–lined plate or baking sheet, cover loosely with plastic wrap and freeze until well chilled and firm, but not fully frozen, 30 to 60 minutes.
3. 3 In a stand mixer fitted with paddle attachment, add the chilled pork paste, garlic, shallot, fish sauce, cornstarch, baking powder, pepper, and 2 tablespoons (30ml) of the prepared annatto oil. Beat mixture on low speed until combined, 1 minute. Increase speed to high and beat for another 2 minutes. Cover bowl with plastic wrap (or transfer mixture to a clean bowl and cover) and refrigerate to let flavor develop, at least 4 and up to 24 hours.
4. 4 Line a rimmed baking sheet with parchment paper or aluminum foil. Divide pork mixture into 10 even portions, just shy of 2 ounces (60g) each. Coat gloved or ungloved hands lightly with vegetable oil. Roll each portion of pork into a 5-inch log around the base of each bamboo skewer and place on prepared baking sheet. If mixture is too soft during shaping, divide portions onto a sheet tray and freeze briefly until firm, but not fully frozen, about 20 minutes. Once shaped refrigerate until ready to grill.
5. 5 For the Scallion Oil: In a medium bowl, combine scallions, oil, salt, and sugar. Cover and microwave until heated through and bubbling, 60 seconds. Carefully uncover and mix well; set aside until ready to use.
6. 6 For the Pork Peanut Sauce: In a small saucepan, heat oil over medium-high heat until shimmering. Add shallots and cook, stirring, until slightly softened, about 1 minute. Add garlic and cook until fragrant, about 1 minute. Add ground pork and cook, stirring to break up the meat, until cooked through and lightly browned, about 3 minutes.
7. 7 Reduce heat to medium and add chicken broth, peanut butter, and hoisin sauce. Cook, stirring frequently, until well blended and warmed through, about 5 minutes. Add sugar, fish sauce, and 2 tablespoons (30ml) annatto oil and cook for another 2 minutes. In a small bowl, mix cornstarch with 1 tablespoon (15ml) water. Stir cornstarch mixture into sauce and cook, stirring frequently, until thickened, about 3 minutes. Transfer to a serving bowl.
8. 8 For the Egg Roll Wrappers: Set egg roll wrappers on a work surface and cover with a damp towel. Working with 1 egg roll wrapper at a time, roll into tight cigar-shaped logs.
9. 9 In a medium saucepan, heat oil over medium-high heat to 350°F (175°C). Use tongs or spider skimmer to gently transfer 5 to 6 shaped wrappers to the hot oil and fry, turning and gently separating as needed, until golden brown and crispy all over, about 3 minutes. Transfer to a paper-towel lined plate and repeat with the remaining wrappers in batches of 5 or 6 at a time; set aside until ready to serve.
10. 10 To Cook on a Grill: For a Charcoal Grill: Light 1 chimney full of charcoal . When all charcoal is lit and covered with gray ash, pour out and arrange coals on one side of charcoal grate. Set cooking grate in place, cover grill, and preheat for 5 minutes. Clean and oil grilling grate. For a Gas Grill: Turn all burners to high, cover, and heat grill until hot, about 15 minutes. Leave primary burner on high and turn off other burners. (Adjust primary burner as needed to maintain grill temperature of 375 to 425℉ (190 to 220℃).
11. 11 Brush skewers with annatto oil. Set skewers on the cooler side of the grill and cook over indirect heat, turning every 2 minutes, until cooked through, 7 to 8 minutes. Move skewers to the hotter side of the grill, and cook over direct heat, turning every minute, until charred on both sides, 3 to 4 minutes. Transfer to platter and hold until ready to serve.
12. 12 To Cook in an Indoor Oven: Adjust oven rack to middle position and heat oven to 375°F (190℃). Brush pork paste skewers with annatto oil on both sides. Bake for 10 minutes. Remove from oven. Brush again with annatto oil and continue to bake until cooked through, about 10 minutes. Transfer to platter and hold until ready to serve.
13. 13 To Serve: Arrange lettuce, herbs, garlic chives, fried egg roll wrappers, and grilled pork paste skewers on a serving platter. Drizzle scallion oil and scatter half of chopped peanuts over the grilled pork paste skewers. Scatter remaining chopped peanuts over the pork peanut sauce and add ground chile, if desired.
14. 14 To form one roll, dip one sheet of rice paper into a wide shallow bowl of warm water, making sure rice paper is completely wet before shaking off excess water. Lay rice paper on a plate and let sit until pliable, about 30 seconds. Arrange any combination of lettuce and herbs just below the center of the rice paper.
15. 15 Remove pork paste from skewers and slice in half lengthwise. Place one slice of the grilled pork paste on top of roll fillings. Top with garlic chives and fried egg roll wrappers. Starting with the edge closest to you, carefully lift the rice paper wrapper over the filling, fold in the left and the right sides, then roll tightly to form the finished rice paper roll. Enjoy with the pork peanut dipping sauce and pickled vegetables, continuing to form rice paper rolls with your guests until fillings are used up.
