Notes

If you are cooking steaks while you prepare the sauce, you can add any juices from the meat to finish the sauce.
Treat your mushrooms right. Please wipe them rather than washing them, and season after they have cooked for best results!
If you flame your sauce, PLEASE don't turn your back on it
Leftovers/ Storage
Fridge – Keep your sauce Diane in a airtight container or jar for up to 3 days.
Reheating – Bring to a simmer in a frying pan over a gentle heat. If you need to, add a splash of cream of milk to loosen the sauce.
Freezer – I do not recommend freezing, as the mushrooms will lose their texture and the sauce may split.
