  • Instant Pot Pressure Cooker



  • In a medium-sized saucepot, bring milk, sugar, cornstarch, salt, lemon zest and salt to a boil, stirring constantly.
  • Once the mixture comes to a boil, remove from heat. 
  • Combine 2 eggs and 2 egg yolks in a mixing bowl. Slowly add the hot lemon custard mixture a little at a time to the egg mixture, whisking constantly. This will prevent the eggs from cooking. 
  • Whisk in butter until melted, then add lemon juice. Stir until smooth and creamy.
  • Pour equally into 4 8-ounce oven-safe ramekins, leaving about 1/2" space at the top. Cover each ramekin with aluminum foil.
  • Place trivet in Instant Pot and add 2 cups water.
  • Carefully place ramekins in the Instant Pot (3 on the bottom forming a triangle and 1 over the top in the center). 
  • Place lid on Instant Pot and set tab to "sealing". Set to "manual" and set to "high pressure" for 5 minutes. 
  • When the time is up, do a quick release and turn Instant Pot off. Allow ramekins to cool to room temperature and then place in refrigerator for a minimum of 2 hours.
