I used to grow Meyer Lemons, they take as long as a year to ripen and are pretty picky to conditions but it's well worth the cost. To me they are by the far best lemon, they pair well with many cocktails and foods (including salads!). They are more on the sweeter side compared to regular lemons, so don't confuse them for a "lemon lemon". I pop one or two slices into ginger ale and it complete changes the flavor to a more complex tropical flavor.
