My favorite thing to do is buying dried Carolina reapers and dried ghost peppers. These can be bought from various outlets. The reapers are more fruity and the ghosts are more smoky.
Dice 2-4 of them up and add them to water to boil for pasta or ramen such as Samyang 2x Spicy Ramen. I include favorite veggies to the water such as broccoli, carrot and peas. When the water boils add the pasta.
When done, drain through a fine sieve but ensure you retain some of the water before draining. Return all the ingredients from the sieve to the pot and add sauce. This could also work for leftover Italian tomato sauce and meatballs/sausage where you may already have veggies such as peppers, onions and mushrooms.
Reheat so all are to temp and eat. It's a major kick of heat that satisfies the heat palate with minimal investment in time. Since you can control the sauce/ingredients, you can make this as healthy as you want. The key is boiling ingredients with the dried peppers but not losing them down the drain when you drain the water. You get most of the heat with all the seeds and skin and ingredients absorbing the heat while they boil.
Quick, easy and you can still get a capsaicin endorphin rush. 🔥🔥
