Pineapple & Ginger juice

I had a pineapple which I had forgotten, so I cut it , cleared the rotten part and put it in a mixer to make juice out of it. Then I also had a piece of ginger. I then google these and came out with this:

1 pineapple
75 gr. fresh ginger
3 lemon
0.5l water
sugar

Mix the pineapple
cut the ginger in small pieces, rinse it and mix it in the water
Add the ginger, pineapple, lemon juice and sugar in a bottle if possible.
Let it rest for a few hours, serve and enjoy !
In the original recipe, it said to also use a handful mint leave and vanilla, but since I had none, I can't tell you how it would taste. But without these, it was just perfect !
