After almost two months, Soviet agents came up with a recipe for what is now called spy dust. Combine all ingredients over medium heat and stir until smooth. Increase heat until crystallization begins. Add 1 oz. Remove from heat and let stand until fire burns itself out.
Scrape pan thoroughly and mash mixture with mortar and pestle.
Add 1 lb. The Soviets never bothered to apologize to anyone. Not to Rive Gauche's owner-chef, not to the CIA, nor even to Escoffier. But, like all great recipes, spy dust had a price for which it could be bought.
