The main and probably only thing I miss bring vegetarian is real gummy sweets. For ages I've had to buy vegetarian Haribo, which is not only hard to find but also nowhere near as good as regular Haribo. Recently Haribo brought out Funny Mix which is good but you're stuck with cola bottles, stars and strawberries (and a strange texture). So I am ridiculously happy that Goody Good Stuff have brought out an amazing new range of gummy sweets. Not only are they gelatine free, but also fat, dairy, and gluten free and of course taste absolutely amazing. The sweets are made with natural flavorings, which really shines through in the taste. Hopefully they become more widely available because even if you're not vegetarian or vegan they taste great and save you from eating animals hooves and other nasties. I've only tried the Cheery Cherries, Sour Fruit Salad and Koala Gummy bears so far but i've just brought all 8 varieties, for research purposes, obviously.
You can now find them in most Holland and Barrett stores :)
