Replacing heavy cream with half-and-half radically alters the emulsion, frequently causing the dairy fats to separate from the boiling sugar syrup due to lower fat content. Achieving a stable sauce requires understanding that excess moisture introduces graininess by prematurely recrystallizing the sucrose molecules before they can reach the desired amber hue.
Transform chilled leftovers by gently warming the sauce in a double boiler before drizzling it over day-old pound cake or stirring spoonfuls into morning oatmeal. Proper storage relies entirely on airtight containers to prevent ambient moisture absorption, which degrades the velvety mouthfeel.
