Since turnips are bitter enough, it’s interesting to cook it with a sweeter vegetable like sweet potatoes. If you already have Panch Phoran ready to use, just add it instead of the fennel, nigella, cumin, mustard and fenugreek in this recipe.
Preheat oven to 325°F. Chop vegetables into (more or less) equal pieces. Place chopped vegetables, ground turmeric, whole spices and ½ the fat in a bowl. Salt and pepper. Mix well.
Spread vegetables evenly and attractively on a roasting dish. Pour remaining oil onto the vegetables.
Place the roasting dish in the center rack of the oven. Roast until cooked to your liking, between 1¼-1½ hours.
Garnish with ground Garam Masala and lemon quarters.
