Fresh Orange & Grapefruit Juice

Freshly squeezed citrus juices are not just Vitamin C bombs, but complex enzyme cocktails. The distinctive tartness of grapefruit comes from naringin, while the sugar in oranges balances it out. Chemically, oxidation begins immediately after juicing, breaking down vitamins and altering the flavor profile, so 'freshness' here is a matter of molecular stability.

Ingredients

Equipment Needed

  • Juicer or Slow Juicer
  • Cutting 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 fiber and pectin, it tastes bitter. Pure fruit flesh gives the sweetest juice.
2

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

Tip: A slow (masticating) juicer heats the juice less and introduces less oxygen than a centrifugal one, preserving vitamins and flavor.
3

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

Tip: Due to its density, honey won't dissolve in cold juice and will just settle at the bottom. Pre-dissolving ensures even sweetness.
4

Stir well and consume immediately.

Tip: Once cells are broken, enzymes start working. After 15 minutes, the flavor may flatten and the color darken.

Recipe FAQ

Why is the juice bitter?
If you press the white pith (albedo) as well, bitter compounds (naringin, limonin) get concentrated. For a sweeter taste, fillet the fruit before juicing.
Can I keep it in the fridge?
Max 24 hours in a sealed bottle, but Vitamin C content drops drastically every hour due to light and oxygen. It's best drunk immediately.
