Homemade Birch Syrup
PREPARATION:
Find a tree which still has mouse ears (leaves which are just starting to unfold). The easiest method involves sawing off a branch from the birch tree and tying a bottle which will hold 3 cups (0.75 l) of liquid to the branch so that it sticks down into the bottle. It is important that the branch should drop slightly downwards.
Collect the sap from the trees after a couple of days.
Sieve the sap and pour it into a pan which can hold 1½ gallons (6 liters) of liquid. Boil the sap over a medium heat until 1 per cent of the sap remains.
