Can I substitute another cut of meat for the flank steak?
We wouldn’t recommend it. Beef brisket, the other possibility, takes much longer to cook through and requires a very long resting time.
Do I need to alter the recipe for a 6-quart electric pressure cooker?
Yes, turn the cooker off immediately after the pressurized cooking time and let the pressure release naturally for 15 minutes; do not let the cooker switch to the warm setting. Use the browning (not the simmer) setting to simmer the sauce in step 5.
