What is the difference between key limes and limes?

Key limes – the name comes from their close association to the Florida Keys – are also known as West Indian lime, bartender’s lime, Omani lime, or Mexican lime (Citrus x aurantifolia). Key limes are smaller, seedier, tarter, and have a thinner rind than the Persian lime we purchase regularly at the store. The Key lime is picked while green and turns yellowish as it ripens. Persian limes (Citrus x latifolia) are what we think of as regular limes and commonly available for purchase in local grocery stores, have fewer seeds, are sweeter, and are larger in size.

Tips and variations for making this Key Lime Fudge Recipe:

● Double boiler – The only thing you have to watch for is that your chocolates are melting at pretty much the same rate in the double boiler. And please use a double boiler and do not try melting the chocolate in a microwave. The double boiler will prevent burning and hardening, and the microwave… does not.
● Zest the key limes from the lime rind before extracting the juice. The difference between the lime peel and the lime rind is that the peel includes all parts of the exterior of the lime, including the white pith. The rind is the color that you zest.
● The two (2) large key limes should render the four (4) tablespoons of juice necessary to make this recipe.
● Substituting limes for key limes will make this less sweet-tart. Not a bad thing. Some people mix ½ lemon juice, ½ lime juice to approximate the taste of key lime juice.
● Do not overcook – As soon as the chocolate chips melt, add the sweetened condensed milk, give it a stir, and get it off that heat.
● This is not a key lime pie fudge recipe. That would involve a bottom layer crust, usually Graham cracker crust. If you would like to add that, make certain it is baked before proceeding with this recipe.

● If you plan on making 36 servings, that is cutting 6 rows x 6 rows. If you plan on making 25 servings, that is cutting 5 rows by 5 rows.
● Place one sheet of parchment paper across the pan. Place the second sheet of parchment paper across the first sheet (to form an +).
● It is best if the rest of the ingredients are not altered as they specifically complement or counteract each other in the perfect manner. I would not be able to offer any other suggestions as substitutions that would work in the same manner.
● Fudge can be stored in the fridge or freezer in an airtight container. It will last up to two weeks in either situation. Do not store fudge at room temperature.
