Not all juicers are created equal — the amount of juice extracted varies from brand to brand. The weight ranges for the ingredients below will ensure that you have enough juice.

　　

Ingredients

Makes about 6 1/2 cups

　　4 to 5 pounds Granny Smith apples

　　3 to 4 pounds carrots, peeled and trimmed

　　1 (6-inch) piece peeled fresh ginger

　　

Special Equipment

a juicer (see cooks' note, below)

　　

Step 1

Slice apples. Process enough slices in juicer, skimming and discarding any foam, to measure 4 cups juice, then transfer juice to a pitcher. Process enough carrots, skimming and discarding any foam, to measure 3 1/2 cups juice, then add to pitcher with apple juice. Process ginger, then stir 2 1/2 tablespoons ginger juice into pitcher. Chill until cold, about 2 hours.

　　

Step 2

Serve over ice, if desired.

　　Cooks' note:

　　If you don't have a juicer, you can substitute 3 cups nonalcoholic sparkling cider for homemade apple juice (flavor will be sweeter than Granny Smith apple juice). Increase carrot juice to 4 cups and use a good-quality fresh juice (not canned). Juice ginger by finely grating, then forcing pulp through a fine-mesh sieve.
