Kilju is a traditional finnish alcohol drink
It's made of sugar, yeast and water
It's illegal to make Kilju in Finland but it might be LEGAL in YOUR country ;)
Step 1: Ingredients
2 Dl sugar
2 teaspoons yeast
1 litre water
Mix all ingredients into the bottle.
The water should not be warmer that +30 degrees because the yeast "dies"
Here's a picture of the indgredients (well you don't really need the mushroom, it only symbolises the yeast =D )
