Valentine's jam tarts

Whether or not you're sharing this Valentine's day with a significant other, there's always time to enjoy a good bake. I like the slightly tragic aspect of the finished product, I think it reflects the pressure and ultimate failure to conform on this commercial 'holiday' (is it even a holiday? I still had to go to work today.)

This is a foolproof family recipe, originally in ounces so have provided rough conversions too!
