Wash, peel and chop apples. Take them in a microwave safe bowl, cover them and cook for 10 mins. You can cook in stove top too, take apples in a saucepan, add ½ cup of water, bring everything to a boil. Cover with a lid and simmer till the apples are completely cooked through.
Now use a masher to mash the cooked apples. you can mash it completely or leave it chunky.
Add sugar and mix well.
Now transfer this entire thing to a kadai and cook on a medium heat. Cook till it gets thick and leaves the sides of the kadai. It will take around 15 to 20 mins.
Switch off the flame and add some lemon juice. Mix well.
Transfer this to a container and let it cool.
Store in an air tight container.
Notes
