Ingredients :

• Dried hibiscus flowers — Hibiscus sabdariffa flowers — not just any hibiscus variety. You can easily find them in African, Caribbean, or health food stores. They should be an intense burgundy red, not brown: if they lean towards brown, they’ve lost their acidity. Plan for about 20 to 30 grams per liter of water, depending on the intensity you want.
• Cinnamon sticks — Whole sticks, not ground cinnamon. Powder clouds the infusion and gives a bitter taste that’s hard to control. Two medium-sized sticks are more than enough — cinnamon tends to dominate if left for too long.
• Cloves — Four or five, no more. Cloves are generous: too many, and they crush everything else. Ideally, you should sense them at the back of the palate without being able to put your finger on it immediately.
• Gelatin — In sheets if possible — they provide a smoother texture and are easier to measure than powder. For a jelly that holds well but remains wobbly, use 6 sheets (about 10 g) per liter of liquid. If you prefer a firmer texture, add one more sheet.
