* Garbage bowl: allocate a mixing bowl on the counter to collect garbage and drop cuttings and other refuse in there. Saves you from having to go to the trash bin every time.
* Preheat watery vegetables in the microwave. Things like onions, mushrooms, etc. are mostly water, and you can avoid having to wait for them to reduce in a pan by nuking them for 2 minutes in the microwave first.
* When boiling water or cooking almost anything in a pot, cover it with the lid! It will trap the heat inside the pot and boil/cook faster. So many people don’t use the lid just to save themselves from having to wash it. The only time not to use the lid is if you need to reduce the liquid or allow volatiles to escape.
* Cooking bigger batches of food takes essentially the same amount of time as smaller batches. Make portions big enough that you can get at least two or three more meals from it.
* Learn to use your oven! Too many people get enamored with single use gadgets when the oven already does so many things. People complain that it takes too long to heat up but it really doesn’t.
* Keep your knives sharp: Do NOT use an electric sharpener, just a simple drag over a stone every few months is probably all you need. A sharp knife is SAFER than a dull one.
* Throw away all cutting boards not made of wood or plastic (dump the plastic too if you’re concerned about it). Any cutting board made of glass, marble, metal, or any other hard material is destroying your knives.
