Preheat oven to 475°F.
In a large bowl, mix cumin seeds, honey, rose harissa, melted butter, olive oil, and ¾ teaspoon kosher salt until combined.
Add the carrots and toss well to coat them evenly.
Spread the carrots in a single layer on a parchment-lined baking sheet, using two sheets if necessary to avoid overcrowding.
Roast for 12-14 minutes until carrots begin to brown and caramelize. Remove from oven and let cool slightly.
Just before serving, toss the roasted carrots with chopped cilantro, pomegranate seeds, and lemon juice. Adjust salt if needed and serve immediately.
