You are going to have to take care to pluck just the blossoms from the stems and branches. All green parts of the plant and the roots are to be avoided. They are inedible.
1 bottle of vodka
a lot of fresh elderflower blossoms
a small handful of fresh coriander seeds and blossoms
Set whichever glass jars you aim to fill on the counter and fill with as few or many elderflower blossoms as possible. The more, the better. Be sure you're only placing the blossoms in the jars, not any stems, stalks, roots, or green parts of the plant. Add a small handful of fresh coriander seeds and blossoms to each container. Fill to the absolute top with vodka. It there is any air remaining at the top of the container the blossoms will brown more quickly than they would otherwise. Place in a dark place - the darker the better, for at least four days. Strain the vodka through a fine strainer (I find ~8 days to be my preference) - when it is fragrant, and flavorful. If you keep the flowers in the vodka, the flavor will change day after day, you can strain it when you like, really. It will keep, refrigerated, after straining, for a good stretch.
