Muddling strawberries is a simple technique that enhances their flavours in cocktails. Start by removing the stems and cutting the strawberries into smaller pieces. Place the strawberry pieces in a sturdy glass or cocktail shaker. Use a muddler or a wooden spoon to gently crush and press the strawberries, releasing their juices. Be careful not to over-muddle, as it can result in a bitter taste. Once muddled, you can add the strawberries to your desired cocktail recipe.
