Inspired by the inventions of the Weasley twins in the Harry Potter books, these two-sided confections are the perfect blend of hot and cool. Eating the red half will cause the heat to rise in your head. Cool the heat by biting into the blue half. This version of Fever Fudge may not affect muggles as strongly as it does wizards.

Stock your own Skiving Snackbox using these candies, some bloody good Nosebleed Nougat, and delightfully nauseating Puking Pastilles.

Step 1: Ingredients

3 cups white chocolate chips
1 can sweetened condensed milk (14oz.)
Red paste, powder, or gel food color
Blue paste, powder, or gel food color
1 teas cinnamon
cayenne pepper--amount varies; 1/2 teas for low-grade fever, 1 teaspoon + for hospital wing
1/2 teas vanilla extract (mint extract can be substituted if you'd prefer a frostier cool side)
loaf pan
parchment paper or foil
spray oil

Step 2: Pan Prep

Line your pan with foil or parchment paper. I lined my pan with a strip of parchment paper in this way to make it easier to take pictures of the process. Grease the foil and/or uncovered areas around the parchment.

Step 3: Bring on the Heat

Place your white chocolate chips in a medium microwave safe bowl. Pour sweetened condensed milk over the chips.

Microwave at 30 second intervals, stirring in-between until the chips are thoroughly melted and the sweetened condensed milk is incorporated.

Pour approximately half of the molten fudge into another microwave safe bowl. Set aside.

To one half of the fudge, add cinnamon, desired amount of cayenne pepper, and red food coloring. Stir to blend in the color. Continue to add red food coloring until the desired shade is reached. You may also want to test spice levels as well. Adjust the amount of cayenne pepper, testing as you go, until you get the appropriate heat level.

Pour red, spicy fudge into the loaf pan. Tap the pan on the counter to level the top and release air bubbles. Refrigerate until set.

Step 4: The Cool Side

One the red fudge is set, warm the uncolored half of the fudge by mircowaving and stirring as before, until the fudge is runny.

Add the 1/2 teas vanilla (and/or mint) extract and some blue food coloring. Stir until the food coloring is mixed in. Add more blue coloring until the desired shade is reached.

Pour the blue fudge over the red and chill until set. The heat from the warm blue fudge should be enough to "weld" the colors together at the joint.

Step 5: Cutting the Pieces

Once fully set, remove the set fudge from the pan. Trim the fudge to make nice squared-off edges.

Slice into long strips. Lay these two-toned strips on their sides and cut into even pieces.
