Cut the pears and potatoes in quarters. Separately, mix the curry, chopped cilantro, cilantro seeds, mustard seeds, sesame seeds, and paprika. Place the potatoes and pears in a bowl and season with salt and pepper to taste. In a heated saucepan, add a little olive oil, then add the quartered potatoes and pears and brown them on all sides. Remove them from the saucepan and coat each quarter with the curry mixture, taking care to cover each piece completely.
