You love fresh citrus but tossing those rinds seems so wasteful. SpendWithPennies.com offers a few ways to put them to good use:
-- Zest a lemon, dry it (Google how) and mix it with pepper for lemon pepper seasoning.
-- Mix 2–3 tablespoons of grated lemon zest into about a cup of olive oil and let marinate for two weeks or so. Shake every so often. At the end of the two weeks, strain out the zest for lemon-infused olive oil.
-- Let some citrus peels steep in your tea.
-- Throw lemon rinds or orange peels in vinegar and let the citrusy scent infuse it.
-- Citrus peels will deodorize a garbage disposal.
-- If you have ants or other pests coming in through door frames, windows or other cracks, place citrus peels in their path and they will run in the other direction.
