Check out this one from Hot Face Sauces. Their Scorpion Scorcher hot sauce certainly has a kick to it. Made with 21% Trinidad Moruga Scorpion Chillies and 16% Scotch Bonnets it has a nice solid burn that lingers for a good while, but on top of this is a lovely sweet tomato flavour that makes it taste delicious.
It won’t melt your face off completely (I have had hotter Naga based sauces), but this one encapsulates flavour and burn and is well worth checking out.
Grab it from Hot Face Sauces’s website for the bargain price of £3.99 http://hotfacesauces.co.uk/product/scorpion-scorcher/
