Perfectly tender California artichokes made in the pressure cooker — no babysitting required. Serve with a squeeze of lemon and your favorite dipping sauce.
Halve the lemon. Cut one half into 4 wedges and set aside for serving. Keep the other half whole for rubbing.
Trim the artichokes one at a time, rubbing the cut lemon half over all cut surfaces as you work to prevent browning. To trim, use a serrated knife and trim the stem flush with the base. Cut about 1 inch off the top to expose the heart — you should see some lavender or purple color. Then, trim the sharp tips from all the outer leaves with kitchen shears.
Add 1 cup of water to the Instant Pot. Squeeze the juice from the lemon half you used during trimming into the water, then add the spent lemon half to the pot. Add bay leaves, if using.
Insert the steam rack. Place the artichokes cut-side up in a single layer on the rack. Lock the lid and set the valve to seal. Cook on High pressure for 20 minutes. Allow about 8 minutes for the pot to come to pressure.
When the cook time is up, allow the pressure to release naturally for 15 minutes, then release any remaining pressure manually.
Transfer the artichokes to a plate and let cool for 5 minutes. Wearing gloves or using a spoon, scoop out the fuzzy choke and discard — leave all the flesh intact.
Season with kosher salt. Squeeze the reserved lemon wedges over the artichokes, letting the juice run between the leaves and down into the heart.
