Every kitchen has one cupboard where things go to be forgotten. It is almost always the corner. You know there is a slow cooker in there somewhere.
Why corner cupboards waste so much
The opening is narrow and the space behind it is wide, so the only way to reach the back is to remove everything in front of it. Anything that takes four steps to reach effectively does not exist.
Fix one: the turntable
A sturdy turntable is the cheapest fix and often the best. Spin it and the back comes to you. Measure the cupboard's internal depth and buy the largest diameter that still clears the door frame - most people buy one too small.
Fix two: pull-out baskets
Wire baskets on runners slide the whole contents out to you. They need a flat base and a bit of patience to fit, but they turn the least usable cupboard in the kitchen into one of the most usable.
Fix three: use it for what you rarely need
If a proper fix is not possible, stop fighting it. Put the things you use twice a year in there - the big roasting tin, the Christmas platter - and give the everyday items the easy cupboard instead.
Fix four: split it front and back
Front half for what you use, back half in a single labelled box you can pull out whole. One box out beats fifteen items out.
Measure before you buy anything
Internal depth, internal width, and the width of the actual opening - which is usually much narrower than the cupboard. The opening is what decides what will physically go in.
Be honest about it
I bought a two-tier corner turntable that would not fit through the cupboard opening. The cupboard was wide enough. The door frame was not, and I had not measured that at all.
