One thing I could afford however was some Asterix Popping powder, which is based on the magic potion that gave them their strength!
I wondered if it might have a taste of the actual magic potion but after looking up what some of its ingredients might be, which includes herbs and lobster, I am slightly doubting this.
On trying it, it has a lovely creamy strawberry flavour with a slight sourness that gets stronger as you get close to the bottom of the packet.
I want a few more of the stickers and for the price I bought it (under a pound) for the popping candy plus a sticker, it's a great price. The only disappointing thing is that it didn't give me super human strength. Maybe you have to eat more than one packet for it to take effect...
