ysl rouge volupte is a look best mixed with blackberries

I am in love with YSL`s Rouge Volupte lipstick & homemade blackberry jam.  To make the jam:

Blackberries (however many you want, frozen or fresh!) in a pan.  Pour a generous amount of sugar until the blackberries are covered (but not so you have to dig to find them).  I use organic light brown sugar.  Heat on low until sugar begins to melt (this will take awhile so go read a book) and then stir every-so-often.  When all the sugar is melted your jam will be ready to be put into a glass jar and placed in the fridge.  It is better than anything you could buy at the store (& healthier, within reason!).  You can adjust the sugar amount through trial and error (I use less sugar now but I use the jam everyday so it goes quick).  More sugar = longer lasting.  I tend to make a new batch each week or every two weeks.
