A baker creating delicate fondant decorations might prefer the control offered by gel or powder, while a cook adding color to a sauce might find liquid coloring more convenient.
Creating Blue Food Coloring from Natural Sources
The vibrant hue of blue, so often achieved with artificial dyes, can also be summoned from nature’s palette. Harnessing the power of plants and algae, we can craft our own blue food colorings, adding a touch of natural artistry to our culinary creations. While not always as intensely saturated or as shelf-stable as their synthetic counterparts, these natural alternatives offer a unique depth of flavor and a connection to the earth.
Butterfly Pea Flower Extract
Butterfly pea flowers, with their striking indigo blossoms, offer a captivating source of natural blue. Their color intensity is influenced by the pH level; acidic environments shift the color towards a purplish-pink, while alkaline conditions deepen the blue. This sensitivity provides opportunities for creative culinary experimentation. To create a blue extract, steep a handful of dried butterfly pea flowers in hot water for about 15 minutes.
The longer the steeping time, the more intense the color. Strain the mixture, and you have a beautiful, naturally blue liquid ready to color your food. The resulting color is a soft, delicate blue that deepens when mixed with alkaline ingredients. It’s important to note that this color is less vibrant and stable than artificial blue food coloring, fading faster in light and potentially changing hue with different pH levels.
Blue Spirulina Extract
Blue spirulina, a type of cyanobacteria, offers a more robust and stable blue color compared to butterfly pea flowers. Its deep, almost electric blue, comes from phycocyanin, a pigment with antioxidant properties. To create an extract, blend a tablespoon of blue spirulina powder with a small amount of water until smooth. Strain the mixture through a fine-mesh sieve to remove any remaining powder.
This creates a concentrated blue liquid, perfect for adding a striking color to various dishes. However, the strong taste of spirulina might not be suitable for all applications. Its intense color, though stable compared to butterfly pea flower extract, can still be affected by light exposure over time.
Comparison of Natural and Artificial Blue Food Colorings, How to make food coloring blue
Artificial blue food colorings, such as Brilliant Blue FCF, generally provide a more intense and stable color than natural alternatives.
