Two UK outlets present the same basic claim: coffee can taste better during brewing if drinkers add a single “unlikely” ingredient that is reportedly common in the kitchen. The Daily Express describes the tip as coming from coffee experts and frames it as a way to enhance flavor. The Mirror likewise says the method makes coffee “so much better,” with an additional emphasis on reducing bitterness. While both articles agree that the ingredient is easy to find and that the change occurs during the brewing process, neither summary provided here specifies which ingredient it is. Both pieces position the advice as a simple home adjustment rather than a change to equipment or beans, targeting everyday coffee drinkers who may want a smoother cup. Overall, the shared narrative is that a one-ingredient addition during brewing can improve taste and may lessen bitterness, though the exact ingredient and the supporting evidence are not included in the text provided.
