If you need a really good Kahlua, why not try to make it yourself. Here comes a good recipe for a bottle of the finest Kahlua for your next The Big Lebowsky theme night. The Dude will love this stuff.
All you need to make a bottle Kahlua substitute:
350 ml Dark Rum
500 ml. strong quality coffee (I used twice the normal strength)
1 fresh vanilla bean (split and take out vanilla)
2 dl sugar
– Make the coffee in a pot and dissolve sugar and vanilla in it.
– Let it cool a little and add the rum. Pour into your nicest bottle and seal it.
– Leave it be for about three weeks in a dark place but shake it a bit whenever you pass it
The good thing about this homemade Kahlua is the freshness. Keep it in the refrigerator in an airtight glass-bottle and it will last longer. Maybe a year or two?
