Surprisingly delightful showcase for blackberry cordial. The muddling of the blackberries and fine straining is a baffling mystery to me - what's the point?! Skeptical of the outcome, I used Korbel brandy. Tried it again with Pierre Ferrand 1840 and it was too Cognac-forward, believe it or not, disrupting the clarity and harmony of flavors. You may beg to differ.
