It's really easy to make. Well, this is the first time for me and so far it looks easy. You just need to find a spruce in the spring with lovely spring green shoots, pick a liter of them (ask for permission of the land owner if you don't own the tree; luckily we have two in our yard), give them a rinse, layer them with sugar in a glass jar, give it a gentle shake (I shook it quite much, just for the fun of it), and put it on the window sill for a month (north or east facing). Not remembering the recipe I put my jar on a south facing sill, but I guess the end result is just the same. Some recipes talk about boiling, but IMHO it would boil away all the goodies (vitamins etc.). So I won't boil it after sieving it. Lovely before-after pictures IMHO!
Honestly, this should be very healthy!!! The jar the next day, June 1.
