I've been very organised this week to make cooking less stressful so I made twice as much mashed potato yesterday as I need and I have the leftovers in the fridge. Today I have made a double quantity of white sauce (half for a pasta bake and half for a fish pie). I also have a mix of smoked and unsmoked fish chopped up from the fish counter. I have peas and sweetcorn in the freezer.
So, in order to assemble my fish pie can I just put the raw chopped up fish in a dish and mix with frozen peas and sweetcorn and white sauce and cover with the mash from the fridge? If so does anyone know how long it should be in the oven and at what temperature as all the ingredients will be cold?
Thank you...sleep deprivation is making me unable to think for myself at the moment!!!
