Prep the endive: Trim the base of each endive and gently separate the leaves. Rinse and pat dry.
Choose the larger, cup-shaped leaves for filling.
Toast the walnuts: In a dry skillet over medium heat, toast walnuts for 3–4 minutes until fragrant. Cool, then chop. This step boosts flavor and crunch.
Prep the fruit: Dice the pear or apple into small pieces.
Toss with lemon juice to prevent browning and add brightness.
Make the filling: In a small bowl, combine crumbled blue cheese, half the walnuts, and half the diced fruit. Add a few cracks of black pepper. Mix gently so the cheese stays chunky.
Assemble the bites: Spoon a small mound of the mixture into each endive leaf.
Don’t overfill—aim for one to two bites per leaf.
Add the finishing touches: Drizzle lightly with honey. Sprinkle with remaining walnuts and fruit. Add herbs if using, and a tiny pinch of sea salt only if needed.
Serve right away: Arrange on a platter in a single layer.
Keep a few extra assembled leaves on standby to refresh the tray.
