Let's Make Fudge!
- Set Up Your Space
- Line your pan with parchment, leaving some hanging over the edges - these become handles later! Get all your ingredients measured and ready - this recipe moves quick once you start.
- The Sugar Mix
- Pour your evaporated milk, sugar, and salt into a pot. Turn the heat to medium-high and start stirring. Don't walk away - this is your arm workout for the day! When it starts boiling, set your timer for 8 minutes.
- The Magic Moment
- Take your pot off the heat and dump in those marshmallows and white chocolate. Now stir like crazy! It'll look lumpy at first but keep going until everything's melted and smooth. Add your lime goodies last - the smell is amazing!
- The Waiting Game
- Pour your fudge into the pan and smooth the top. Now comes the hard part - waiting! Give it a couple hours to set up, or stick it in the fridge if you're impatient like me.
Tips From My Kitchen
Let me tell you what I've learned from countless batches: Fresh lime zest makes all the difference - those little green flecks are gorgeous. If you can't find key limes, regular limes work just fine. Keep stirring that sugar mixture or it'll burn on the bottom - trust me, I've been there! And don't rush the setting time, or you'll end up with fudge pudding instead of squares.

Mix It Up
Sometimes I add coconut to make it taste like a tropical vacation. White chocolate chips with a touch of green food coloring make it extra festive. During the holidays, I'll press some crushed graham crackers on top for that key lime pie feel. My kids love helping with the decorating part!
Keeping It Fresh
Store your fudge in the fridge in a covered container. It lasts about two weeks - if your family doesn't eat it all first! For gifting, I cut it into cute little squares and layer them between wax paper in pretty boxes. Just take it out of the fridge about 10 minutes before serving to let those flavors really shine.
Frequently Asked Questions

Yes, though key limes are more aromatic. You'll need more regular limes to get same amount of juice.

Watch for soft-ball stage - drop of mix in cold water forms soft ball. Or just boil 5-6 minutes, stirring constantly.
- → Fudge too soft?
Might need longer cooking time. Sugar needs to reach right temperature to set properly.
- → Can I freeze it?
Yes, wraps well and freezes up to 3 months. Thaw in fridge overnight.

A delightful dessert combining the tangy zest of key limes with creamy white chocolate. Perfect for summer gatherings and sweet-tooth cravings.
