Orange & grapefruit juice

Freshly squeezed citrus juices are not just Vitamin C bombs, but complex enzyme cocktails too. The characteristic tartness of grapefruit comes from naringin, while the sugar content of the orange balances this out. Interestingly, oxidation starts immediately after juicing, breaking down vitamins and changing the flavour profile, so 'freshness' here is a question of molecular stability.

Ingredients

Equipment Needed

  • Juicer or slow juicer
  • Chopping board and sharp knife
  • Glass

Instructions

1

Peel the fruits with a sharp knife, removing as much of the white pith (albedo) as possible.

Tip: Although the white part is full of fibre and pectin, it tastes bitter. Pure fruit flesh gives the sweetest juice.
2

If using a slow juicer, separate into segments before feeding. If using a centrifugal juicer, larger pieces are fine.

Tip: A slow juicer (masticating) heats the juice less and introduces less air (oxygen) than a centrifuge, resulting in slower vitamin degradation and a fuller taste.
3

If using honey, dissolve it beforehand in a little warm water, then stir into the finished juice.

Tip: Due to its density, honey does not dissolve in cold juice, it just settles at the bottom. Pre-dissolving (making a syrup) helps achieve even sweetness.
4

Stir and consume immediately.

Tip: Once the cells are ruptured, enzymes begin to work. After 15 minutes, the taste may be flatter and the colour darker.

Recipe FAQ

Why is the juice bitter?
If you juice the white pith (albedo) as well, the bitter compounds (naringin, limonin) concentrate in it. If you want it sweeter, remove the pith before juicing.
Can I keep it in the fridge?
For a maximum of 24 hours in a sealed bottle, but Vitamin C content drops drastically every hour due to light and oxygen. It is best to drink it immediately.
