• Peel oranges using a peeler. Try to peel thinly avoiding to take out the pithor white skin.
• Clear and discard the pith using a knife.
• Finely slice the peels and keep aside to add to marmalade,
• Slice oranges in roundles then stack up together and cut finely. This is an easy and quick way.
• Next, add sugar to it(castor/coconut sugar), and keep covered for an hour.

Instant Pot Method to cook Marmalade

• When ready to cook, add about 1 cup water and PRESSURE COOK for about 10 min.
• Do the quick pressure release and then set the SAUTE MODE on, for about 20 minutes on MEDIUM. You can do the setting on HIGH also but since there is chance of sugar getting caramelized and burning at the bottom of the pan, I keep it to medium.
• Keep on stirring it. When it starts to thicken, do the Ice Cold Plate test.
• Keep a plate in freezer section of refrigerator few minutes before testing.
• To check, drop some marmalade on the plate and tilt it. If it stays Marmalade needs no more cooking. If it is runny, cook for some more time.
• IF it starts to harden or thick, add some orange juice or water and mix.
• Once marmalade is cooked, take out the inner pot from Instant Pot to stop further cooking.

Cook in Stove-top Pressure cooker
