Prep your orange cups
Cut oranges in half and carefully scoop out the flesh. Try not to tear the peel—this isn’t a crime scene. Set them aside like little citrus bowls.
Heat the cream and sugar
Pour cream and sugar into a saucepan. Heat over medium, stirring until the sugar dissolves completely. Bring it to a gentle boil, then let it simmer for about 3–4 minutes.
Add the magic (orange juice)
Remove from heat and stir in fresh orange juice (and zest if using). This is where the magic happens—the acid helps it set naturally. No gelatin needed.
Pour into orange peels
Carefully pour the mixture into your prepared orange halves. Don’t overfill unless you enjoy risky balancing acts.
Chill and wait (the hardest part)
Refrigerate for at least 4 hours, or until set. Overnight is even better if you can resist sneaking a spoonful.
