Elderflower Cordial, First Step.

(Sarah) Beeny's Restoration Nightmare has an episode, where the family are cutting Elderflower blossoms.  They intend to make cordial.  It reminded me that I had a hope to do so at some stage.  My sister in law had given me a few slips from her bush and I have a few growing now.  We tidied up a garden bed today and have planted numerous slips in the hope that they will grow and prosper.  When I see some blossoms, I will have to research how to make Elderflower cordial.  My sister in law successfully brewed cordial a year or two ago.
