We have split our harvest and Mr GBT has his earmarked for two gallons of wine to add to the Hobbity Booze Cellar. Due to current time constraints they have been frozen for now and having done this for the last two years, I can confirm, that the flowers come to no harm when they are used later.
I, meanwhile, have a batch of cordial brewing- this year I am tweaking a couple of recipes to try and get a combination that's right for my personal taste so I have added a couple of oranges in addition to lemons. In the spirit of waste not want not and my naturally gnat bottomed outlook the orange slices can be eaten afterwards and I suspect the same goes for the lemon as it's all been soaking in a sugar syrup. Double duty now that's what I like to hear! The remainder of the blooms are being dried for elderflower vinegar. For this you need to fill a jar with the dried blooms and then cover them completely with cider vinegar. Store in a warm, dark place for three weeks before straining. Good for use in salads.
