Place the raw cauliflower florets into a food processor, and pulse several times, until it has a grainy, rice-like consistency. Season with sea salt, freshly ground black pepper, and any additional seasonings if desired. Set aside.
Set the Instant Pot on saute mode and add the coconut oil to the pot. When melted, add the riced cauliflower and stir for 1–2 minutes, until the “rice” starts to soften.
Press cancel and transfer the cauliflower rice to an oven-safe bowl that will fit into the inner pot of the Instant Pot.
Add 1½ cups water to the inner pot (there’s no need to wash the bits of leftover cauliflower out of it) and place a trivet at the bottom. Place the bowl with the cauliflower rice on the trivet.
Secure the Instant Pot lid and move the vent knob to the sealed position.
Set the Instant Pot to “Manual” and cook on high pressure for 5 minutes.
Quickly release the pressure and remove the lid.
Add salt and pepper, seasoning to taste.
