INSTRUCTIONS Add butter to the Instant Pot. Using the display panel select the SAUTE function. When butter is melted, add onion to the pot and saute until soft, 3-4 minutes. Add wine to the pot and deglaze by using a wooden spoon to scrape any brown bits from the bottom of the pot. Add broth, cream, salt and herbs to the pot and stir to combine. Carefully fan the pasta in the pot (this helps prevent clumping) and ensure it is completely submerged. Add the halved cherry tomatoes in a single layer--do not stir. Turn the pot off by selecting CANCEL, then secure the lid, making sure the vent is closed. Using the display panel select the MANUAL or PRESSURE COOK function*. Use the +/- keys and program the Instant Pot for 5 minutes. When the time is up, let the pressure naturally release for 5 minutes, then quick-release the remaining pressure. Gently stir the pasta, breaking up any clumps. Fold in smoked salmon pieces and serve immediately garnished with freshly ground pepper and additional herbs.
