Using low setting, sauté onions for 2-3 minutes, adding broth or water in small amounts as needed so they don’t stick. Add garlic and cook for another minute. Add 1/2 of the spices, sweet potatoes, carrots, celery, and raisins. Cook for another minute or two. Stir in lentils and broth. Cover and set for manual, 10 minutes pressure. Turn off when done and allow pressure to come down naturally.
