Conclusion

C.I.P Plum Pie

Today we went over to the school garden and picked plums. 

We also Picked up rubbish to make the school cleaner and more healthy.

What I would like to do with the plums is make a plum pie. 

Here is a photo of what some types of plum pies look like.

Now I have a craving for plum pie ugh!!!

Here is the recipe of plum pie if you would like to make plum pie.

1. In a large bowl, sprinkle plums with lemon juice. Combine the sugar, flour, salt and cinnamon. ...
2. For topping, in a small bowl, combine the sugar, flour, cinnamon and nutmeg; cut in butter until crumbly. Sprinkle over filling.
3. Bake at 375° for 50-60 minutes or until filling is bubbly.

What I like about plums is that they are juicy and sweet but not to sweet at the same time.

but what I don't like about plums is that they stain clothes very easy.

If you don't know what to put in a blog post here is some help.
