A brandy sour at heart, this cocktail builds depth through unexpected layers. The cognac provides a warm, rounded base while muddled strawberry and elderflower bring a soft, floral sweetness. A touch of cinnamon syrup adds spice, and the balsamic vinegar contributes a subtle, tangy complexity that keeps the drink from veering too sweet. The result is rich and fruit-forward, with enough acidity and earthy undertones to maintain balance.
