Step 1

Pour the water or wine into an Instant Pot. Set the pot’s rack (with the handles up) or a large, open vegetable steamer inside the pot. Set the fillets skin-side down on the rack or in the steamer, arranging them so they overlap as little as possible (do not stack them). Set two barely overlapping lemon slices on each fillet. Sprinkle the fish and lemon slices evenly with the pepper and salt. Lock the lid onto the cooker.
