I hate plastics and avoid buying food packaged in it.  But this stuff I actually buy in the plastic squeeze bottle.  I bought it in the metal can once and the experience of cleaning the sticky can off every time I used it, and never being able to  re-close it properly, cured me of that.  The squeeze bottle is best for containing and using Lyle's.  if you've never tasted Lyle's  golden syrup, you should.  I use it as a recipe substitute for corn syrup,, since my daughter is  severely allergic to corn.
