It’s best to avoid oranges that are shrivelled or have mouldy spots or blemishes. Also, as the colour of the skin is affected by different temperatures, the brightest-coloured oranges aren’t necessarily the ripest.
The tastiest oranges are firm and heavy for their size; and have a sweet, fresh fragrance when smelling the skin.
Fresh oranges can be stored at cool room temperatures for 2 to 3 weeks, and refrigerated for 1 to 2 months.
Once peeled, they should be stored in a tightly closed container to keep out moisture and odours.
