Step 1Remove any dirt or insects from the elder flowers. Do not wash as you don't want to wash off the pollen which will give it flavor.
Note: If fresh elderflowers are no longer in season, you can use 15 to 20 g (0.5 to 0.7 oz) of dried elderflowers instead, or to taste.
Step 2Use scissors to trim the thick stalks off the elderflowers and place into a large pot filled with 2 liters of water.
Step 3Use a vegetable peeler to remove the outer yellow layer of the lemons and add to the pot. Juice the two lemons and add the lemon juice to the pot. Add the citric acid.
Step 4Place on the stove. Heat up until simmering, and then cover with a lid and take off the heat. Let it sit for at least 4 hours of up to 24 hours to allow the flavors to infuse.
Step 5Strain the liquid through a colander lined with a muslin cloth or a nut milk bag. Squeeze any remaining liquid from the flower & lemon pulp for even more flavor.
Step 6Place the pot with the elderflower liquid back on the stove. Add the sweetener, bring to a boil and stir to combine. Simmer for 20 to 30 minutes, or until you get about half of the original volume, about 1.5 liters of liquid.
Note: If you don't want to reduce the liquid, see the tips in the recipe above. My pots have capacity marks inside so it's easy to get exactly the amount I need.
Step 7Meanwhile, sterilize as many glass bottles and a funnel (see tips in the recipe above to learn how to do that).
Step 8Bottle up the elderflower cordial while it's still hot. Keep the bottles in a cool, dark place for up to 12 months.
Step 9Serve 2 to 4 tablespoons combined with a cup of still or sparkling water and some ice.
Step 10Once opened store in the fridge and use within 2 weeks. Optionally, serve with a slice of lemon for some extra zing!
