If your hazelnuts aren’t toasted, bake them on a tray at 350°F (175°C) for 8–10 minutes until fragrant, then rub off most skins in a towel and roughly chop.
Make the hazelnut-thyme crunch: In a small bowl, combine chopped hazelnuts, thyme leaves, lemon zest, a pinch of salt, and a few cracks of pepper. Set aside.
Prep the celeriac and apple: Toss the matchsticked celeriac and apple with half the lemon juice to prevent browning.
Whisk the dressing: In a large bowl, mix mayonnaise, crème fraîche (or yogurt), Dijon and whole-grain mustards, white wine vinegar, honey, 1 tablespoon (15 ml) olive oil, remaining lemon juice, 1/4 teaspoon (1.25 ml) salt, and black pepper to taste.
Combine: Add the celeriac, apple, and parsley to the dressing. Toss to coat well and let stand 10 minutes to lightly soften and meld flavors. Adjust seasoning with salt and pepper.
Assemble: Separate endive leaves into cups. Spoon the remoulade into the leaves, drizzle with the remaining 1 tablespoon (15 ml) olive oil, and top with the hazelnut-thyme crunch. Garnish with a few extra thyme leaves and serve immediately.
