Wah cherries, remove stems and pit. I slice in half as well, to keep the chunks smaller.
Place cherries, lemon juice and sugar in the Ninja Foodi.
Stir and then let rest for about 10 minutes. This allows the sugar to start to break down the cherries.
Stir again. Place Pressure lid on Ninja Foodi and move valve to seal position.
Turn Ninja Foodi on and select Pressure. Set to High for 2 minutes.
When timer beeps, let pressure natural release for 15 minutes and then quick release remaining pressure.
Turn off pressure cook function and open lid.
Turn on sauté function on high. Stir mixture, it will be runny but do not panic.
Mix corn starch and water together well. I use a Ball pint size freezer jar (will repurpose later to freeze the compote), as I can just add the ingredients and shake to mix well.
Once compote starts to boil, pour in corn starch mixture and stir continuously for about 5-10 minutes. Compote will start to thicken up.
Turn off Instant Pot and let cool for 30 minutes
Even after 30 minutes this will be very hot. Carefully ladle jam into freezer containers. I do multiple small ones so I can pull this out at a moments notice.
Store in the fridge for up to 30 days, or once cooled freeze for up to 6 months.
