Food Coloring from Cabbage
This homemade food coloring is prepared from red cabbage. Because red cabbage pigment is pH-sensitive, it starts out purple but turns pink when combined with acid and blue when combined with alkaline substances.

- 1 small red cabbage, chopped
- 1 cup water
- ¾ cup (150 g) white granulated sugar
- ½ teaspoon lemon juice, plus extra for pink color
- ¼ teaspoon vanilla extract
