The gorgeous green color of avocados can be tricky to preserve; as soon as you cut into them, exposure to the air begins the oxidation process, which turns the flesh brown. But there is a trick that lets you cut your avocados in advance and still keep them fresh and green.
Fill a large bowl with water, and squeeze the juice of one lemon into the water. As you cut the avocados, put them cut side down in the water. You can also use this trick for peeled avocado slices, as long as you keep them fully submerged. Put the whole bowl in the fridge, and it will keep the avocados green for hours.
