Modern Light Flan
Why this recipe works
- Smooth custard: Straining the egg and milk mixture before baking removes bubbles and any small cooked egg pieces for a finer set.
- Balanced sweetness: The caramel brings depth and sweetness, while lime zest adds freshness without turning the custard sharply citrusy.
- Gentle baking: A water bath surrounds the custard with steady, indirect heat, helping it set evenly rather than becoming rubbery.
- Best made ahead: Chilling gives the custard time to firm fully and allows the caramel to loosen into a pourable sauce.

Timing notes
- Chill thoroughly: The flan needs at least several hours in the fridge before unmoulding; overnight gives the cleanest slices.
- Unmould just before serving: Turn it out close to serving time so the caramel runs over the custard while the texture stays neat.
- Cool before chilling: Let the baked custard come to room temperature before refrigerating to protect its delicate set.
Texture tips
- For a silkier finish: Pour the custard through a sieve and into the dish gently to avoid trapping excess air.
- Keep the centre wobbly: Take the flan from the oven when the edges are set but the centre still has a slight wobble; it will continue to firm as it cools.
- For neater slices: Chill overnight before cutting and wipe the knife between slices for a cleaner presentation.
Common mistakes
- Taking the caramel too far: Watch the caramel closely once it turns golden; it can move from deep amber to bitter very quickly.
- Adding hot milk too quickly: Whisk the warm milk into the eggs slowly so the custard stays smooth rather than scrambling.
- Unmoulding too soon: A warm or only partly chilled flan is more likely to slump or break when turned out.
Ingredient notes
- Use whole milk: Whole milk gives enough richness for a smooth custard while keeping the dessert lighter than versions made with cream or condensed milk.
- Fresh citrus zest matters: Fresh lime zest gives a clean aroma that dried citrus peel cannot match; lemon can be used for a slightly different lift.
- Vanilla sets the tone: With so few ingredients, a good vanilla extract or vanilla bean paste noticeably improves the flavour of the custard.

Ingredients
Instructions
- Heat the oven to 160°C (320°F). Put a kettle on to boil, and set a 20 to 23 cm baking dish or cake pan inside a larger baking dish for a water bath.
- Make the caramel: put 200 g caster sugar and 60 ml water in a saucepan over medium heat and swirl to moisten. Cook without stirring for 6 to 10 minutes until deep amber, then immediately pour into the baking dish and tilt to coat the base evenly.
- Warm the whole milk in the same saucepan over medium heat until steaming and just starting to tremble at the edges, then take off the heat. Let it stand for 2 minutes so it is hot but not boiling.
- In a mixing bowl, whisk the eggs with the vanilla extract, a pinch of fine sea salt, and the finely grated zest of the lime. Slowly whisk in the warm milk in a steady stream so the eggs do not scramble.
- Strain the custard through a sieve into a jug or bowl, then pour it gently over the set caramel. Place the dish in the larger baking dish and pour in enough just-boiled water to come halfway up the sides.
- Bake for 45 to 55 minutes until the flan is set around the edges but still has a slight wobble in the centre. Carefully lift it out of the water bath and cool to room temperature.
- Cover and chill for at least 3 hours, or overnight, until fully cold and firm. To unmould, run a thin knife around the edge, place a serving plate on top, then invert in one confident motion and let the caramel run over the custard.
Recipe notes
Tips
- For the cleanest slices, chill the flan overnight and wipe the knife between cuts.
- When making caramel, watch the colour closely in the final minute; it goes from golden to bitter very quickly.
- Eggs in desserts should be fully cooked; this flan is baked until set, but if serving vulnerable groups, ensure the centre reaches a firm set with no liquid custard.
Substitutions
- Replace vanilla extract with vanilla bean paste for a slightly richer vanilla flavour.
- Replace lime with lemon for a different citrus lift while keeping the custard fresh.
Storage
- Refrigerate up to 3 days
- Keep covered in the fridge. For best texture, store unmoulded and turn out just before serving; the caramel will loosen as it sits.
