Pour the water into your Instant Pot (mine is a 6 quart) and add the trivet or a cooking rack.
Add the ground beef, side by side, on top of the trivet.
Set the Instant Pot to Manual, high pressure, for 18-20 minutes (18 if your blocks are thinner, 20 for thicker blocks in the middle).
At the end of the cook time, turn the Instant Pot off. Do a quick release and drain the water from the Instant Pot (I like to use my trivet to hold the meat in the pot as I dump out the water).
Using a strong metal or wooden spoon, crumble the ground beef. This will take a few minutes! It's okay if your beef isn't cooked right through as we're going to be cooking further.
Turn the Instant Pot to saute and add the ½ cup water, cumin, garlic, paprika, salt, onion powder, black pepper and cayenne and stir until thoroughly combined, adding an additional ¼ cup water if necessary.
Serve immediately, refrigerate for up to 3 days, or freeze for up to 3 months.
