Line a baking sheet with parchment paper and get all of your ingredients together so you can work quickly.
In a small heavy bottomed saucepan, combine the sugar, honey, sea salt, water and Sriracha. Give it a good stir and place the saucepan over medium heat. After a minute of stirring, add the sesame seeds.
Keep cooking, stirring pretty much constantly while the sugar starts to become golden amber.After 5 minutes, clip a candy thermometer to the side of your pan to start keeping an eye on the temperature. Keep stirring! Don't let the bottom get too dark or the whole batch will have a burnt taste.
Somewhere between 5 and 7 minutes, the temperature should reach about 275 degrees. When it does, remove the pan from the heat and working quickly, stir in the vanilla, butter and the baking soda. Combine well and immediately pour the mixture carefully onto your parchment lined baking sheet.
Allow the brittle to cool for about 15 minutes. I know, I know, it's going to be a long 15 minutes, but for safety reasons...you must control yourself! Once cooled, break the brittle into bite-size pieces and enjoy!
Notes
(These notes are important...please read!)
Please be careful when working with hot sugar. Seriously, it's the hottest thing your skin will ever meet in the kitchen. Do not attempt to lick any spoons in this recipe and I suggest not making this with children. They can help taste-test when fully cooled.
As stated above, getting all of your ingredients out and measured, or at least having all of your tools beside the stove top will help. You will need to stir continuously, and once the mixture gets to that point of being done, you will want to work quickly (but carefully).
