I have been meaning for quite a while to blog a recipe which uses blackberries – we have a whole ice cream tub full left over from last year, and the blackberry season is already upon us! Blackberry and apple crumble being one of my favourite desserts I felt I couldn’t justify not doing this recipe first. Since this is a blog about frugal food and blackberries are free for almost everyone, they are everywhere after all, this seems like an ideal ingredient to use.
