Preheat oven to 275 degrees. In a small saucepan, combine syrup, sriracha, and butter/oil; bring to a boil and stir until combined. Toss with crackers and fresh herbs of your choice.
Spread onto a parchment-lined rimmed baking sheet. Bake until coating is set, about 45 minutes, stirring every 10 minutes to not let them burn. Let cool completely before serving. The crackers can be stored for up to a week in an airtight container.
