Wash the strawberries and pat dry. Cut the stems and leaves.
Chop the strawberries into small pieces.
Add the chopped strawberries to a skillet or deep bottom pan and add sugar and mix well. Ensure all strawberry pieces are covered by sugar.
After some time, water will be released by strawberries.
On low flame/heat, heat the skillet with chopped strawberries and sugar.
After 5 minutes, add lemon juice. Mix well and let it simmer till the jam thickens.
After some time, you will see the strawberry syrup bubbling, make the gas/heat on medium heat.
Keep stirring in between to avoid sticking to the bottom of the utensil. You will notice that the color of the puree changes from light pink to beautiful deep pink. At this stage you must stir often in between else it will stick to the bottom.
To check if the jam is ready, drop few drops of the jam on a plate and run your finger to check the consistency. It should not be runny.
Transfer the contents into an airtight jar. Next day store it in the refrigerator. This jam stays good for up to 10 days in refrigerator.
