Where can I find nut-free chocolate in the EU?

There is company in UK called Vantage House that supplies cocoa products and cocoa accessories :).

Making your own chocolate is very easy as basic one can be made with just cocoa powder, oil and sweetener (sugar, maple syrup honey anything you want).

If you like taste of some store-bought chocolate you can just use the same ingredients that are listed on the package. In EU you have % content of certain parts so it's very easy to figure out what should go in.

This company will send nut free chocolate worldwide. They appear to be a small family firm that make some pretty robust claims about their nut-free credentials. I'm not connected with them in any way and I can't vouch for how their product tastes either. They're actually called the Nut Free Chocolate People so I'd hope they're true to their word.

If you can't find anything in the shops, try online. A Google search for chocolate sin alergenos (without allergens -- or the accent, but that's a minor issue) from Spain gives me various shopping results on the main page: use the local language for the country you're in and I expect you'd get similar results.

Unless it specifically mentions on the packaging that something contains nuts, it isn't supposed to, at least in the EU.

That doesn't mean there can't be traces of something in it left over from a previous production batch, and many products will warn for that in the case of nuts, but that's it.

That's nothing specific to chocolate btw, the same is true for pretty much all food stuff sold packaged in the EU, it MUST have a list of ingredients.

But if you seriously need to avoid an allergen, best shop only in specialty stores where they know the product better than would a supermarket clerk or someone manning say a gas station.
