A @demonbitters original. Very, very simple. A mix of two great French spirits, Cognac and Calvados, balanced with some homemade citrus shrub and a dash of citrusy bitters. It's amazing that when mixed with spirit the strong vinegar flavour profile of the shrub recedes to just provide a sweet and sour balance.
25ml homemade citrus shrub (lemon, lime and orange)
Dash Bittermens Hopped grapefruit bitters
Shake and strain. Simple. Lemon garnish if you feel fancy. (I usually do).
