Output
"""***Prompt:
 <|im_start|>system
You are a helpful assistant.<|im_end|>
<|im_start|>user
Tell me a recipe for a spicy margarita.<|im_end|>
<|im_start|>assistant

***Generation:
 Sure! Here's a recipe for a spicy margarita:

Ingredients:

- 2 oz silver tequila
- 1 oz triple sec
- 1 oz fresh lime juice
- 1/2 oz simple syrup
- 1/2 oz fresh lemon juice
- 1/2 tsp jalapeΓ±o, sliced (adjust to taste)
- Ice cubes
- Salt for rimming the glass

Instructions:

1. Prepare the glass by running a lime wedge around the rim of the glass. Dip the rim into a shallow plate of salt to coat.
2. Combine the tequila, triple sec, lime juice, simple syrup, lemon juice, and jalapeΓ±o slices in a cocktail shaker.
3. Add ice cubes to the cocktail shaker and shake vigorously for 30 seconds to 1 minute.
4. Strain the cocktail into the prepared glass.
5. Garnish with a lime wedge and jalapeΓ±o slice.

Enjoy! This spicy margarita has a nice balance of sweetness and acidity, with a subtle heat from the jalapeΓ±o that builds gradually as you sip."""
