Our experiments with foraged wrinkly rose extract continue, this time in the form of vividly magenta ice cubes. One of the fascinating properties of our homemade rose extract is its ability to shift colors based on acidity. Depending on how we freeze it, we can create a striking color-changing effect in lemonade or other drinks.
We made a fresh batch of rose extract (check out our process here: Wild Rose Extract) and, instead of acidifying it for long-term storage, we diluted it and froze it into ice cubes. This preserves the magenta hue—until it meets something acidic like lemonade, where it transforms into a vibrant red-pink, swirling beautifully as it melts.
There are two ways to achieve this transformation:
Freezing water-thinned rose extract and adding the ice cubes to lemonade, watching as lilac tones turn pink.
Freezing lemonade or lemon juice into ice cubes and dropping them into lilac-colored rose water, reversing the effect.
Since the strength of the extract depends on the forage, and dilution affects both color and taste, there’s no perfect formula—just trial and error. The goal is to keep the stunning color while avoiding an overpowering floral flavor.
A Note on Ice Cube Trays
We always opt for stainless steel trays over plastic or silicone. Stainless steel doesn’t stain, doesn’t absorb flavors, and eliminates concerns about leaching into our ice. One day, we can make coffee ice cubes; the next, delicate rose ice cubes—without a trace of crossover.
