Storage & ReheatingRefrigerate up to 4 days, or freeze up to 3 months (thaw overnight in the fridge before reheating) — the cream sauce may lose a little of its original silkiness after freezing, but a good stir while reheating brings it back together. Reheat in the microwave, covered with a damp paper towel, for 3- 4 minutes, stirring halfway, until steaming hot — add a splash of milk or stock if the sauce has thickened in the fridge.
