What would make my tzatziki sauce truly exceptional?

Tzatziki is a traditional Greek sauce whose base ingredients comprise salted strained yoghurt, garlic, grated cucumber, dill leaves, and olive oil.
To make your tzatziki truly exceptional follow the steps below:
1) Start by squeezing as much as possible the water out of half a cucumber that has been grated. This is the single most important factor that will make your tzatziki source exceptional.
2) Fine-chop the dill leaves using a knife. The dill must be fresh. The volume of the chopped dill leaves should be about the same as the volume of the squeezed grated cucumber.
3) Mix the cucumber and the dill with Greek strained yoghurt . The latter should have a volume that is three to four times that of the cucumber and dill.
4) Add some salt and smashed cloves of fresh garlic.
5) Add a couple of teaspoons of balsamic vinegar.
6) While stirring the mix, gradually keep adding extra virgin olive oil until the sauce obtains a silky texture.
7) Do not add any other ingredients in the mix.
8) Place the mix in the fridge and keep it for a couple of hours and let chemistry do its magic.
9) Remove the residual water, if any, which may have surfaced.
10) Stir the mix once more final time and serve in smaller containers.
