Yes certainly. One way to make idli without a stand is to pour the batter in greased steel or glass bowls. Then add water to the insert of the instant pot, place a trivet and plate on it. Arrange the bowls and steam for 10-12 minutes. If the bowls are super large, steam longer till a toothpick comes out clean. Alternatively, simply add the batter to the plate placed on the trivet and steam. Cut the instant pot idli into pieces and serve.
