What is the ingredient for making a fireball hot?

It seems you're asking about the ingredients for making a Fireball Cinnamon Whisky shot.

Fireball is a brand of cinnamon whisky liqueur. While the exact recipe is a trade secret, here are the main ingredients:

* Whiskey: The base spirit is typically a blend of Canadian whiskies.

* Cinnamon: This is the dominant flavor, giving the drink its signature spicy kick.

* Sugar: Added to sweeten the drink and balance the cinnamon's heat.

* Other spices: Fireball likely includes other spices, like nutmeg, to create its complex flavor profile.

Please note:

* It is illegal to make alcoholic beverages at home in most places.

* Fireball is a commercial product, and replicating its exact taste at home is extremely difficult.

Instead of trying to recreate Fireball, you could explore other cinnamon whiskey cocktails, or consider making a simple cinnamon syrup to add to your own whiskey drinks.
