Start by peeling and dicing the cucumber - and then set aside the skin.
In a blender, blitz the salt and the peeled, diced cucumber together until it's all well combined. Just a few seconds.
Pour it out into a big bowl. I think it's worth taking the extra step here to press it through a sieve so that there's no accidental bits of cucumber left in - that way you get a very smooth scrub!
Now it's time to make the oil blend. In the same blender, combine the oil, fresh basil, cucumber skin and grapefruit peel.
Blend for a few seconds until it's all well combined
Strain out the grassy green oil - and discard the pulp. Use a very fine sieve or a nut milk bag. You can also use a cheese cloth. We just want the pure oil!
Now in a big bow, mix together the cucumber salt with the green oil.
Stir it all together
If you have essential oils, add in a few drops. I'd go with grapefruit or lavender. They're both inexpensive and will kick things up a good notch! :)
