Thoroughly wash and dry the citrus fruit. Then, using a sharp knife, carefully trim away the top and bottom ends, and any remaining stem or blossom ends, to expose the fruit.
Preparing citrus fruits properly before zesting or juicing ensures you get the most flavor and avoid bitterness from the pith. Here's a step-by-step guide:
Wash the Fruit: Begin by washing the citrus fruit under cool running water. Use a vegetable brush to scrub the skin, removing any dirt, wax, or pesticides. This is especially important if you plan to use the zest.
Dry the Fruit: Thoroughly dry the fruit with a clean towel. This makes it easier to handle and zest.
Trim the Ends: Using a sharp knife, carefully slice off the top and bottom ends of the fruit. This creates a stable base and exposes the flesh.
Remove Any Imperfections: Inspect the fruit for any blemishes, bruises, or remaining stem or blossom ends. Trim these away with the knife.
Zest (if needed): If you need zest, do this *before* juicing. Use a zester, microplane, or vegetable peeler to remove the outer layer of colored peel, being careful to avoid the white pith underneath. The pith is bitter and will negatively impact the flavor.
Juice (if needed): After zesting, you can juice the fruit using a citrus juicer or by hand. Cut the fruit in half and squeeze out the juice.
Roll the citrus fruit firmly on the countertop before juicing. This helps to break down the membranes inside, making it easier to extract more juice.
