Homemade Vanilla Extract

2nd time I make this. I first made it in January 2020 and I still use it now, 5 years later. But it's almost finished and I decided to stop adding vodka to it and just make a new bottle. I'll get extract with a stronger vanilla taste and aroma.

Easiest recipe ever. I used 300ml vodka and about 35g vanilla pods, all cut lengthways. Can't say if it's good yet as I've just put the vanilla in today, but into the cupboard it goes for about 6 months, and I'll try to remember to update this when it's ready.
