As friends of mine from the states, Heat Hot Sauce will charge you a bit more for postage to the UK but they stock a wide range of exciting sauces that you’re unlikely to see anywhere else. Including around 99% of the ones seen on Hot Ones, as well as an amazing, Star Wars-inspired, star fruit blend.
Not everything that I’ve had from them has been great, of course, and I wasn’t thrilled by my first pepperberry sauce, but I was very glad to be able to try it. And Heat have been consistently great about sending me stuff.
If there’s something that you can’t get in the UK or you’re one of my american readers, these guys are well worth shopping with.
