Slices of 1/2 Lemon
1/3 Absolut Citron
Juice of 1/2 Lemon
Fill up with 2/3 Schweppes Lemon
First slice half a lemon in small slices. Then some ice, I prefer alot of ice in this drink. Pour the vodka in, press the rest of the lemon in the glass. Mix around and then fill up with Schweppes lemon. Mix again and you're finished. If you don't got the Schweppes lemon you can always use Fanta lemon instead, but it will be a lot sweeter.
If you want a real Moilanen you should get a 1 1/2 litres plastic bottle, cut it of in the middle and use it as a glass.
