Notes

Storage & Reheating Tips

  • Cooling: Allow the sauce to cool to room temperature before storing to prevent condensation inside the container.
  • Airtight Containers: Transfer the sauce to airtight containers to keep it fresh. Glass or BPA-free plastic containers work well.
  • Refrigeration: Store the sauce in the refrigerator for up to 3-4 days. Make sure the lid is securely sealed.
  • Freezing: If you want to store it longer, you can freeze the sauce. Use freezer-safe containers or zip-top bags, removing as much air as possible. It can be stored in the freezer for up to 2-3 months.
  • Reheating: When you're ready to use the sauce, thaw it in the refrigerator overnight if frozen. Reheat gently on the stovetop over low heat, adding a splash of milk or broth to restore the creaminess and prevent it from thickening too much.
  • Fresh Garnishes: For the best flavor, consider adding fresh parsley just before serving, rather than storing it with the sauce.
