That Sloe bloody Gin

This is mostly a note to myself to get going on the Sloe Gin making.

I have had Sloe's in the freezer since the Visiting The Hamiltons post at the beginning of October, but have yet to make the bloody stuff.

My dad has sent me this recipe which i think is to go into an empty (clean and freshly washed out) 4 pint milk container.
Dad is that correct?
Which makes sense because 1lb of sloes to 4 pints would be similar to the below recipe of 400g of Sloes to 1 litre bottle. (1 litre would be about 2 pints.)
My dads recipe doesn't use so much sugar though.

Recipe taken from this website.
For one empty 1 litre bottle:
1) add approx 400g/14oz sloes (to occupy about half the bottle). Remember to cut or prick the sloes before bottling.
2) add approx 150g/5oz ordinary white sugar (this is about a wine goblet in volume).
3) top-up with gin (about 500ml/1 pint).

Must start some Sloe Gin Mon or Tues.
