What is the heathest dish in world?

It's impossible to definitively say what the "hottest dish in the world" is because:

* Spice levels vary: What's considered "hot" is subjective and depends on individual tolerance.

* No standardized measurement: There's no universally accepted unit for measuring heat in food. The Scoville scale is commonly used, but it's not the only one.

* Constantly evolving: New dishes and challenges push the limits of heat constantly.

However, some dishes are consistently known for their intense heat, and often use ghost peppers (Bhut Jolokia) or Carolina Reaper peppers, which hold the Guinness World Records for the hottest chili peppers.

Here are a few examples:

* The "Ghost Pepper" Challenge: This is a popular challenge where people try to eat a dish with a ghost pepper. It can include anything from pizza to wings to curries.

* "The Reaper Challenge": Similar to the Ghost Pepper Challenge, but using Carolina Reapers.

* Some traditional dishes: Certain dishes from regions like India, Thailand, and Mexico often contain extremely hot ingredients and are renowned for their intense spiciness.

Important Note: Always exercise caution when trying extremely spicy foods. It's essential to start slow and listen to your body. Intense heat can cause discomfort, and even health risks for some individuals.
