Stone Jelly (Ice Powder)

Ingredients

• 200 g ice powder seeds
• 2000 g cooled boiled water
• 10 ml mint juice
• 10 g mint powder
• cheesecloth

Method

Rubbing ice powder seeds in cheesecloth against cold water extracts their mucilaginous compounds — gelatin-like polysaccharides that hydrate and thicken as they dissolve. This is faster and more aggressive than steeping. Start with 2000 ml of cooled boiled water in a large bowl, submerge the cheesecloth bundle, then press and rub it firmly against the bowl's sides for six minutes. You're not being gentle; the friction breaks down the seed coating and accelerates release. The water will gradually turn cloudy and slightly viscous — this is your extraction working. Stop when the bundle feels papery and depleted.

Pour the entire mixture, seeds and liquid, into a clean container and leave it undisturbed at room temperature for two and a half hours. The jelly-making happens here as the released compounds interact with water molecules and form a loose gel matrix. You'll see the distinction between liquid and set quite clearly; the surface will lose its shine and the whole thing will hold a slight tremor rather than slosh. Don't rush this or stir it. Cold temperatures set jellies faster, but room-temperature setting creates the correct texture — patience and the physics of polymer networking matter more than the thermometer.

Spoon the set jelly into a chilled transparent cup. The cold vessel arrests any further breakdown. Add either 10 ml mint juice or 10 g dried mint powder for herbal-infusion; fresh mint juice will integrate more evenly and deliver cleaner aromatics, while powder adds texture and a more muted flavour. Lemon, hawthorn, or mulberry juice are valid substitutes — choose based on what flavour note you want to cut against the mild sweetness of the jelly. Stir slowly and deliberately to combine without breaking down the delicate gel structure. If using ice cubes, add them last so they don't water the drink as they melt.
