Step 1

Put the oil in the pot, select Sauté, and adjust to More/High heat. When the oil is hot, add the onion, oregano, and baking soda and cook, stirring frequently, until the vegetables are tender, 4 minutes. Add the garlic and tomato paste and cook, stirring continuously, until the garlic is fragrant, 45 seconds. Add the wine and cook for 1 minute to burn off some of the alcohol. Press Cancel.

Step 2

Add the tomatoes and their juices, broth, basil sprigs, and cheese rind (if using). Add 3/4 teaspoon salt and several grinds of pepper. Lock on the lid, select the Pressure Cook function, and adjust to HIGH pressure for 40 minutes. Make sure the steam valve is in the “Sealing” position and that the “Keep Warm” button is off.

Step 3

When the cooking time is up, let the pressure come down naturally for 10 minutes and then quick-release the remaining pressure. Discard the basil stems and cheese rind. Add the chopped basil and season the sauce with salt and pepper. Use immediately, or let the sauce cool completely, uncovered, in the refrigerator and store for later use.
