Big agrees. Pear and Cognac together are transcendant! That's why I substituted St George Pear Brandy for the pear vodka in this recipe. (And the fact that I didn't have any pear vodka.) Wonderful glass full of pear bliss! Will definitely be making this again.
I second this substitution. Why spoil the other two, naturally-flavored ingredients with an artificial one?
1/2 oz Poire Williams Pear Brandy
3/4oz Benedictine
3/4oz Cognac
