Homemade Kahlua is an excellent gift, or an excellent reason to host a party. Either way, good imbibing is on the menu.
Add the strong coffee, sugar and vanilla bean to a pot.
Bring the coffee mixture to a boil. Stir to dissolve the sugar.
When the coffee mixture reaches a boil, lower the heat to simmer and cover.
Let simmer, covered, for 20 minutes.
Remove the pot from the heat and remove the lid. Allow to cool to 130°F.
Add the vodka. Transfer the liquor to a pitcher or other easily pouring vessel. With the aid of a clean funnel, fill the cleaned bottles. Seal and store away from light for at least 4 weeks before drinking or gifting.
Enjoy.
