Blueberries and Lime are a perfect combination for jams so why not add additional tartness using Key Limes.
There is a difference between lime varieties and all have different flavors. The three main limes are listed below. The key lime has a very distinctive flavor leaning on a bit of an orangey-lime flavor. They are really good and tart which make them the perfect choice for the traditional Key Lime pie. When you can find them they are usually smaller than regular limes and pretty expensive.
Much smaller than regular "Persian" limes, the key lime ranges in size from a ping-pong ball to a golf ball. The peel is thin, smooth and greenish-yellow when ripe, as is the flesh inside. Key limes have a higher acidity than regular Persian limes with a very distinctive aroma, which makes them valuable for culinary use.
Also known as the Bearss or Tahiti Lime, the Persian Lime is the most common variety found in the United States. Generally larger and less aromatic, the Persian Lime tends to be both less acidic and bitter than some other varieties.
Made famous by its namesake pie, the Key Lime differs from its larger cousin in a number of ways. First, it’s significantly smaller and as a result yields less juice. In addition the Key Lime has more seeds and its flavor is more intense and possesses a bitter component not present in its Persian cousin. Finally, this fruit turns yellow when ripe.
Commonly found in the near east, the Kaffir Lime is extensively used in the cuisine of the region. Often referred to as a Makrut Lime because Kaffir is considered offensive in some languages, this lime can be easily identified by its bumpy texture. This fruit has a very sour flavor and as a result is commonly used as a medicine.
