You'll want more than one packet.
Tasty, tasty, tasty. You really can't stop eating them once you've opened the bag. These are quite delicious flavourful snacks, and not too hot at all (don't be put off by jalapeño). A comfortable heat, a pleasant warmth, and definitely not take your mouth to A&E hot. We used to buy the Chilli & Lemon ones, they are addictive too, but these are even worse. Be warned, you'll be looking for another packet if you only buy one.
