Apple Cider Vinegar with a pinch of soy sauce (Best Option)
1 teaspoon apple cider vinegar + 1/16 teaspoon soy sauce per 1 tablespoon Worcestershire sauceApple cider vinegar provides the necessary acidity to mimic Worcestershire's tang, while a tiny amount of soy sauce adds umami depth that Worcestershire typically contributes. This combination balances the flavor without introducing strong or conflicting notes.
When mixing, ensure the soy sauce is well diluted and use it sparingly to prevent the cake from becoming too salty or dark. Incorporate it evenly into the batter to maintain consistent flavor.
Compared to Worcestershire sauce, this substitute maintains the subtle complexity without altering the pound cake's texture or sweetness, preserving its classic profile.
