My friend who is an avid cook showed me this the other day. Cut the very tips of your citrus fruits off before putting them into a juicer. Instead of catching some of the liquid in the closed ends, the juice will squirt all the way through. Flip over and do it again. Nothing goes to waste.
Double the juice from your citrus. Either let them float in hot water or place in microwave for about 15-20 seconds. Remove and let cool to a temperature that doesn't burn the fingers.
To get more juice out of a lemon, microwave it for 10 or 12 seconds and then roll it on the countertop.
Place lemon(s) in microwave for about 10-20 seconds (based on your microwave) until the lemon is very warm to the touch (almost hot). Wait until you feel comfortable handling the lemon, then cut and squeeze.
