Orange Jam

Scrub the citrus fruits thoroughly with a brush and submerge in boiling water for 5-10 minutes. Using a fine grater or by slicing thinly, zest three of the oranges and lemons, making sure to avoid the bitter white pith.

Juice all the fruits. Do not discard the white pith; instead, wrap it securely in cheesecloth.

In a microwave-safe bowl, combine the juice, 200 ml of water, the zest, and the cheesecloth pouch with the pith. Cover with plastic wrap and microwave on high for 20-25 minutes until the zest is tender.

Carefully remove the cheesecloth pouch, squeeze the extracted pectin back into the juice mixture, and discard it.

Add the sugar, stir well, and microwave on high for another 30 minutes (keep an eye on it to prevent boiling over!).
