. Add the vodka:

Once the mixture has cooled, add the vodka and vanilla extract (if using). Mix well so that the liqueur is homogeneous.

Pour the liqueur into clean, sterilized glass bottles using a funnel.
Close the bottles tightly and shake them gently to mix well.

Before serving, shake the bottle lightly to mix well.
Serving tips:
Serve the liqueur chilled in small liqueur or shot glasses.
It can also be used to flavor desserts, coffee or poured over ice cream for an extra gourmet touch.
Storage:
The liqueur can be stored for up to 2 to 3 weeks in the refrigerator. Remember to shake well before each use to restore a homogeneous texture
