1. In a small saucepan, combine figs and vinegar over medium-high heat. Stir until figs soften and liquid is almost evaporated, approximately 6 to 8 minutes. Set aside and allow to cool.
2. In a large mixing bowl, combine Plugrá Butter and cheese until smooth; fold in the walnuts by hand. Last, fold in the fig mixture so it is "swirled" in the butter mixture to give a marbled effect.
3. Remove butter from bowl and spoon onto parchment paper. Roll into a log, using edge of baking sheet to form a tight log. Chill for 2 hours before serving.
