As for cooking spices...I have been buying bulk spices at my local vegan co-op and copying spices mixes that I have bought in the past. I grind them in my Magic Bullet Blender and you know what...they taste pretty damn good! And no MSG or chemicals!!!
But I miss Swedish Fish, Twizzlers, Chewy Sweettarts, white/yellow cake mix...I have been here for 10 years already, so I have found my own things from the UK that are good subs! Except for the candy, which is lucky for me, so then I just don't eat it! But its a treat when I do go back to the states twice a year...and when my parents come to visit! They always bring me lots of stuff!
