Prepare the Produce: Wash all the carrots thoroughly under cold running water. A vegetable brush is great for this. If they aren't organic, you may prefer to peel them. Trim off the very top and bottom ends. Wash the oranges and lemon (if using).

Peel the Citrus: Using a sharp knife, carefully peel the oranges and the optional lemon. While the peel contains oils, it can impart a bitter taste to the juice, so we remove it. You can leave the white pith on, as it contains beneficial flavonoids. Cut the peeled oranges into segments that will easily fit into your juicer's chute.

Prepare the Ginger: Scrape the skin off the ginger using the edge of a spoon – it's much easier and less wasteful than using a peeler. Chop it into a couple of smaller pieces.

Set Up Your Juicer: Assemble your juicer according to the manufacturer's instructions. Place a large jug or glass under the spout to catch the juice and a container to collect the pulp.

Start Juicing: Turn on your juicer. I find that alternating the ingredients helps everything move through smoothly. Start by feeding a couple of carrots through the juicer.

Add the Ginger: Next, add the pieces of ginger. Follow immediately with another carrot. This helps to push all of the potent ginger juice through the machine effectively.

Juice the Oranges: Now, add the orange segments. Their high water content will help flush out the remaining carrot and ginger flavours from the juicer.

Finish with Carrots: Feed the remaining carrots (and apple, if using) through the juicer. If using the lemon, add it at the very end. Let the juicer run for an extra 30 seconds to extract as much liquid as possible.

Stir and Serve: Give the collected juice a good stir to combine all the flavours. Pour into glasses and serve immediately for the best taste and maximum nutritional benefit.
