After you have picked the honeysuckle flowers, you will need to clean them before using them. A simple way to do this is to submerge the flowers into a bowl of water, gently swishing them around to get the bugs and dirt off. Strain the flowers and remove any green bulb if any are still attached.
Pour the water into a microwaveable jug and heat for 2 minutes. You could also heat the water in a saucepan over medium heat.
Add the rinsed flowers to the hot water. Cover and set aside to steep for at least 2 hours. If you are planning to leave the flowers steep for longer than 2 hours, place the jug in the fridge after it has cooled to room temperature.
Using a sieve lined with a coffee filter, strain the flowers from the water.
After the mixture is very well strained, add the sugar and mix until fully dissolved.
Pour into a glass jar and add the lid.
Store in the fridge for up to a month and use as you would regular simple syrup.
