Lime versus Lemon
It's not a contest
Both limes and lemons are acidic, limes slightly more. Lemons tend to be sour with limes being bitter.
It’s this contrast in taste – both limes and lemons – that bring out the flavor in other foods.
Use limes instead of lemons, and lemons instead of limes. Substitute in drinks, salads, dishes and baked goods. You can also use lime zest (the gratings of the lime rind) for lemon zest.
