Pour condensed milk into jars
Seal tight with aluminium foil
Place trivet in Instant Pot. Pour two cups of water into the inner pot.
Place the sealed jars on the trivet. Ensure that the water comes part way up the side of the jar. Too high and it may condense into the caramel. Too little and it may burn.
Manual high pressure for 25 mins. NPR for 10 and then release.
Take the jars out carefully. Use an oven mitt if you like.
Stir the liquid - it may have a slight curdled, jelly-like appearance.
Serve, gift or eat. There's no judgement here.
