Here it is, the historical recreation of my mothers "White dinner". AKA purposely making bad food to show GAF.
It's on a small white plate for accuracy, no colour allowed in or on the plate! There were many variants of the white dinner and it was available in many many combinations;
Chicken wrapped in foil and put in the oven
Pork Chops wrapped in foil and put in the oven
Fish Fillet wrapped in foil and put in the oven
don't you dare think about grilling or pan frying, adding spices or sauce to any meat.
Over-boiled vegetable could also include marrow, parsnips, green boiled until translucent cabbage.
I learned one thing making this today, how to make bread sauce and it tasted really good (My mothers just came from a packet).
