What is the difference between Persian limes and key limes?
- Persian Limes, those that you find in the grocery store next to the lemons, are typically 2-3 inches in diameter, have thick dark green skin, and a nice lime flavor.
- Key Limes are much smaller, usually 1-½ inches in diameter, have thin, leathery skin, and a very acidic, intense, slightly herbal, lime flavor.
Can I use real key limes to flavor my fudge?
- I really love that this fudge is essentially flavored with real key limes being key lime curd is made with real key limes. If you want to use fresh key limes to make this lime fudge, then you will need to make curd first.
- You could possibly use our vanilla fudge recipe which blends together white chocolate and sweetened condensed milk then add key lime juice and zest to it, but you'd have to adjust the amount of white chocolate to thicken the fudge.
- I have not tried this so I do not know what the ratios of juice to chocolate and sweetened condensed milk would be.
- If you give it a try I'd love to hear about it in the comments below.
- Stir 1 ⅓ cups of key lime curd into white chocolate.
- Melt in the microwave.
- Heat at 70% power for 90 seconds then let the bowl rest in the microwave for about 3 minutes before stirring.
- Add green food coloring and continue to stir until the white chocolate chips melt.
- If needed, you can heat it for an additional 10-15 seconds.
- It's best to allow the residual heat from the hot melted white chocolate to melt the remaining chips.
- Just let the bowl sit for another minute to allow the heat to continue to melt the chocolate then stir again.
- If you overheat the white chocolate, the fudge may become greasy. If this happens be sure to check out our Easy Fudge FAQ page.
- Once all the chips have melted, pour the fudge into an 8-inch pan that is either lined with non-stick tin foil or parchment paper or buttered well.
That's it! This lime fudge is seriously so easy to make and it has such a lovely flavor. No one will ever guess it took you less than 10 minutes to make it.
What type of white chocolate should be used to make key lime fudge?
- I developed this recipe using Nestle Premier White Chips which made a wonderfully flavored fudge.
- Nestle white "chocolate" chips are actually considered a confectionery coating because they are made using vegetable oil (palm kernel oil) instead of cocoa butter which is used to make pure white chocolate.
- You can use pure white chocolate chips (made with cocoa butter) to make this fudge but know that you will need to use more white chocolate than confectionery coating in order for your fudge to set up property and that the lime flavor will not be quite as intense because the flavor of the cocoa butter will mute the lime flavor slightly.
- You can also use other types of white confectionery coating like White Candy Melts, Merckens White Wafers, White Almond Bark, Ghirardelli White Melting Wafers, or Peter's Ice Caps (one of my personal favorites).
- White chocolate is a bit softer than white confectionery coating so you’ll need to adjust the recipe accordingly.
- If using white confectionery coating chips (no cocoa butter listed in the ingredients) use 24 ounces, if using pure white chocolate (with cocoa butter listed in the ingredients) then use 28 ounces.
You can find the Nestle White Chips or Peter's Ice Caps and the key lime curd in a single jar or multi-pack on amazon (commission earned for sales at no extra cost to you).
