HOMEMADE STRAWBERRY JAM

Eh..1 month already since my last post.Woops..I haven't tried much new recipes, until yesterday, with any available ingredients in the fridge. ( I wanted to try banana muffin, but there was no butter..so cant bake any cake nor cookies).
Anyway..i have strawberries. And it turned out pretty much like the one sold in commercial jar ( with less jelly-ish taste. =)

Ingredients :
- a box of fresh strawberry, sliced
- Raw sugar / low-calories sugar. ( low calories one is preferable)
- half of lemon

How to cook :
- Stir strawberry on the pan until it performs lumps. Do not add any water
- After the strawberries are fully smashed, add sugar, taste it accordingly.
- Add lemon water
- Boil it until it becomes thick
- Put it in a glass jar and refrigerate it overnight.
