1. Benefits of Natural Dyes

Avoid synthetic colorants like Red 40 and Blue 1 linked to childhood hyperactivity in Lancet studies. Natural alternatives offer subtle flavor enhancements and antioxidant benefits.

2. Color Mixing Formula

Combine 3:1 ratio of blue butterfly pea tea to beet juice for base purple. Pro tip: Use white plate testing to achieve desired shades:
– Lavender: 4:1 tea/beet ratio
– Eggplant: 1:2 tea/beet ratio

3. Sweet Potato Concentrate

Steam purple sweet potatoes for 15 minutes, then blend with filtered water. This creates a stable coloring perfect for buttercream frostings (lasts 7 days refrigerated).

4. pH-Sensitive Cabbage Dye

Simmer red cabbage (1 cup chopped per 2 cups water) for 20 minutes. Add 1/4 tsp baking soda to convert blue liquid to purple. Ideal for batter-based recipes.

5. Berry Infusion Technique

Mix equal parts blackberry pulp and blueberry juice. Double-strain through cheesecloth for smooth consistency. Freeze leftovers in silicone molds for 3-month storage.
