Step 1: The Lipid-Cream Emulsion

In a large bowl, cream the **softened butter** and **whipping cream** together. The Texture Rule: Do not over-aerate. Unlike a cake, we don’t want significant air bubbles here; we want a dense, smooth paste. Stir in the **peppermint extract** and your **food coloring**.

Step 2: Sucrose Integration

Gradually incorporate the **powdered sugar** one cup at a time. Switch from a whisk to a sturdy spatula or a dough hook. The Clump Prevention: If you add the sugar too fast, the butter will coat the lumps, making them impossible to break. Slow integration is key.

Step 3: Kneading the “Candy Clay”

Once the mixture becomes too thick for a spoon, move it to a surface dusted with powdered sugar. Knead by hand until it is smooth and no longer sticky. The Consistency Target: It should feel like professional modeling clay—pliable but capable of holding a sharp edge when cut.

Step 4: The Extrusion (Shaping)

Divide the dough into four pieces. Roll each piece into a long “rope” about 1.5cm thick. Using a sharp knife or bench scraper, cut the ropes into 1.5cm pillows. Uniformity: Cutting them into equal sizes ensures that the drying time is consistent across the entire batch.

Step 5: Atmospheric Dehydration

Spread the mints in a single layer on a parchment-lined baking sheet. The 24-Hour Rule: Leave them on the counter for 12 to 24 hours. This allows the surface moisture to evaporate, creating a “matte” finish and a stable exterior that won’t stick together in a jar.
