To make spiced pecans, pre-heat oven to 375 degrees. Combine all ingredients (except salt) in a small bowl and toss to combine. Place on a baking sheet lined with parchment and toast until fragrant, about 4 minutes. Remove from heat and cool. Coarsely chop nuts and sprinkle with salt.For livers, rinse in a colander under cold running water for a minute. Transfer to a baking sheet lined with paper towels. Blot livers dry and season generously with sea salt and pepper.Heat olive oil in a large cast iron skillet over medium-high heat until just about smoking. Carefully add chicken livers, onions, and garlic in thin and even layer. Resist the temptation to stir, allow the livers and onions to brown, about 1 minute.Once caramelized on one side, turn chicken livers over and stir onions, reduce heat to medium. Slowly add bourbon and ignite with a long match or stick lighter. Reduce bourbon until almost evaporated, about 1 minute.Add herbs and butter and reduce heat to medium-low. Cook until livers are medium of slightly pink on the center, about 1-2 more minutes. Remove from heat, remove herbs and transfer contents to a food processor. Pulse 1-2 times to give livers a rough chop. Taste and adjust seasoning if needed.Place chicken livers on slices of grilled levain or country bread.Garnish with freshly parsley, mint, and grated lemon zest. A generous drizzle of good olive oil—a few drops of aged balsamic vinegar are nice with this as well. Sprinkle the liver toast with a little more sea salt and some cracked pepper.
