Store leftovers in an airtight container in the fridge. This keeps flavors intact and stops the sauce from drying out. It should last about a week if you keep it tight. Freezing works too if you wanna stash some for later. Just thaw in the fridge overnight and give it a good stir before using. If your sauce thickens too much in the fridge, add a splash of warm water or stock and whisk it smooth again. It bounces back real good without losing flavor. For best texture, don’t double pressure cook the sauce. Make it fresh when you can, but these storage tricks help when you gotta stretch it out.
