Boil water in a pot. Place steamer basket into pot. Place artichokes face down and cover. Steam for 20 minutes.
To Microwave
Put ½ cup water into a microwavable bowl. Place 1 artichoke facedown in bowl. Cover with plate. Microwave on high in 5 minute intervals until soft.
To Instant Pot
Place 1 cup of water in Instant Pot. Place artichokes facedown into steamer basket and place in Instant Pot. Steam for 10 minutes and then manually release the pressure.
For Butter Dipping Sauce
Melt butter and combine with lemon juice and garlic salt.
Notes
It doesn't matter if you place the artichoke facedown or faceup. I like facedown so it doesn't collect water inside the artichoke.
