Red Beet Food Coloring

¼ cup (70 g)

Ingredients

2 medium beetroots , peeled and cut into chunks
1 cup (250 ml) water

Directions

Make the juice

Blend beets and water in a food processor.
Using a cheesecloth, strain the purée into a bowl to extract the juice.

Cook the syrup

Pour the juice into a saucepan and add sugar.
Turn the heat to medium‑high and stir to dissolve the sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Beetroots: Provide the main pigment, which gives the coloring its deep red colour.
White granulated sugar: Thickens the juice into a syrup and helps it keep its consistency.
Lemon juice: Adds acidity that helps stabilise the red beet pigment's colour.

The step that matters

Simmer to a single-thread consistency. Reducing too little leaves the coloring thin and watery, while reducing too far makes it stiff and hard to pour. Stirring in the lemon juice after the heat is off keeps its brightness intact.
