Slice all the oranges in half (do this in batches because of the quantity; you don't want insects perching on them) and start extracting the juice with your juicer. Repeat this until all oranges are extracted. Remember to keep a large bowl where you'll be pouring the juice as you extract because it's a large quantity.

Slice the lemon in two and extract as well. Add to the orange juice extract

Slice the grape fruit in 2 or 4 depending on the size and extract as well. Add to the orange and lemon juice extract

Slice the tangerine in 2 as extract as well. Add to the orange, lemon and grape fruit juice extract

Now use a blender to blend the ginger (add little water) (I didn't peel it bcoz I wanted all the nutrients locked in) then sieve it using a filter. Add the juice to the citrus blast above.

Finally, add honey (quantity as desired) store in plastic bottles and keep refrigerated. Enjoy your week with this very healthy drink.
