Over the last few years there has been a growing movement within the cocktail bar scene for using homemade ingredients. Creating your own infusions, bitters and tinctures can offer a chance to be creative and unique in the cocktails you’re making. But there can be a downside to this as well. I always think of the practice of creating your own ingredients as being similar to the way a chef works with new products, but the big difference is that a chef is (usually) trained as a professional to handle ingredients in a safe way. Often when a bartender starts working with exotic herbs, spices, barks and berries they are doing so as an interested amateur.
I was judging a cocktail competition last year and one of the competitors presented a homemade chorizo infused tequila. When the judges quizzed him about how he had infused it, he replied that he has simply added sliced chorizo to tequila and allowed the flavour to infuse over a period of several days. It occured to me that he was thinking about combining flavours that would work well, but hadn’t thought about how to handle these ingredients in a safe way. Leaving a meat product sitting at room temperature, or even more likely on a hot back bar, for several days has the potential to make your customers seriously sick. Even infused in a strong spirit there is a chance that bacteria cultures could grow and lead to food poisoning. Had the bartender researched the idea of infusing meat into a spirit he would have found that there is a safe way of doing this, through fat washing, and would have produced a product that was safe to serve to customers, especially if stored correctly.
