3 litres of olives. Or enough to fill the container below.
10% salt water i.e. 200 gm salt and 2 litres water
An empty used plastic 2 litre containers e.g. fruit juice or clean milk plastic containers.
Half a cup of vinegar, more or less.
Place the olives you have into the plastic containers.
Add the salt water to fill the container, covering the olives. Leave a little space e.g. 2 cm room at the top.
Screw on the cap tightly.
ONE WEEK LATER
The plastic container will have swollen and we don’t want it to split, so let some gas out but keep some pressure in the container thus keeping bugs and air out.
THREE MONTHS LATER
Try one. They will most likely be too strong.
Decant half of the liquid and add water and some vinegar. Leave for a bit and taste again. If still too strong dilute further.
