This food coloring makes for a great presentation but not sure how we would react palate-wise. Found the spray can coloring on the German food cooperative, The Deli Garage. The finishes come in gold, silver, red and blue. They are completely harmless to eat and are flavorless with no food dyes nor ethanol. Not available to U.S. market as yet maybe awaiting FDA approval. Incidentally, you can follow The Deli Garage on Facebook as well.
