1-First, prepare your ingredients by peeling and chopping the carrots, sweet potatoes, onions, and apple into 1-inch pieces; this setup makes cooking smooth and efficient.

2-In a large pot, melt the unsalted butter over medium heat, then add the chopped onions and sauté until they turn translucent and fragrant, which takes about 5 minutes.

3-Stir in the curry powder, chopped carrots, sweet potatoes, and apple, cooking for another 2 minutes to let the flavors mingle.

4-Pour in the chicken broth, add the salt, and bring the mixture to a boil; then reduce the heat and let it simmer for about 20 minutes until the vegetables are tender.

5-Use an immersion blender or transfer the mixture to a blender to puree until smooth, stirring in the honey and freshly ground black pepper to taste for a touch of sweetness and zing.

6-Finally, adjust the seasoning as needed and serve hot, perhaps with a sprinkle of extra curry powder on top for added depth.
