Hints on storage of vegetables and fruit
This can actually get into a lot of detail. Especially if you consider that advice for your home may not work for mine. In England I could store butter on the counter, whereas here I need to keep it in the fridge lest I come home to a small puddle.

Some of the very basics off the top of my head:


Leafy greens are best stored at 12 degrees Celsius. For those in warmer climates, better 4 degrees than 24.
Salad vegetables (cucumbers, tomatoes, peppers, carrots etc.) can be stored in the fridge for longer life. In my experience this doesn't affect their flavour.
Root vegetables (onions, potato, beetroot etc.), except carrots, can be stored at room temperature, even when it's warm. 
Potatoes should be stored in the darkest place possible.
vegetables from the solanum family (tomatoes, aubergines and peppers) should be kept apart from the squash family (cucumbers, courgettes, pumpkins). I can't remember why this is, though it causes the squash family to spoil faster.


There's plenty more, but I can't think of them right now.
