Combine dried seafood in a medium bowl and cover with warm water; let soak until soft, about 1 hour. Drain seafood and transfer to a food processor along with the garlic, lemongrass, and shallot. Process into a coarse paste. Add wine, sugar, bean paste, and soy sauce and pulse to combine.
Heat peanut oil in a 12″ skillet over medium-high heat. Add seafood mixture and cook, stirring occasionally, until caramelized, about 20 minutes. Add 1/2 cup water and cook, stirring, until evaporated, about 5 minutes more. Stir in sesame oil and transfer mixture to a clean jar; let cool to room temperature, cover, and refrigerate for up to 1 month.
