Glaze or, in French, glacé, is a simple technique that requires time as the main ingredient. The goal is to boil unsalted beef stock until it is a thick, syrupy and shiny sauce. We recommend making your own stock for glazes, but if you use store bought, be sure it is sodium-free or the final product will be extremely salty as a result of the reduction process. Glazes like this one have any number of uses, but this one has a snap of spicy ginger along with the slightly astringent quality of coriander seeds that is extremely nice with tender cuts of beef. Use it sparingly as the flavor is intense.
