Prepare the CrustIn a medium bowl, combine sugar, salt, milk, rice flour, and vegetable oil. Mix until a soft, pliable dough forms (about cookie‑dough texture). Cover with cling film and let rest for 20 minutes to hydrate.

Form and Prebake the CrustAfter resting, press the dough into a tart tin or shallow pie plate, lining the bottom and sides evenly. There’s no need to bake—a no‑bake tart works beautifully, but if you prefer a firmer base, blind bake at 170 °C for 10 minutes.

Make the Lemon CustardIn a saucepan, whisk lemon zest, sugar, cornstarch, and lemon juice until smooth. Add egg yolks and stir again. Cook gently over medium heat until thickened, stirring constantly. Remove from heat, stir in the butter until silky smooth. Cover directly with cling film to prevent a skin and allow cooling in the fridge.

Prepare the Creamy ToppingWhip the heavy cream until soft peaks form. In another bowl, beat the cream cheese with sugar and lime zest until smooth. Gently fold the whipped cream into the cream‑cheese mixture. Add a drop of food coloring for a pastel lime hue if desired.

Assemble the TartOnce the lemon custard is completely chilled and set, spread it evenly over the crust. Gently spoon or pipe the lime‑cheese cream over the custard, smoothing with a spatula. Chill in the fridge for at least 30 minutes before slicing.

Can I use wheat flour instead of rice flour?Yes—though crust will be denser. Almond flour adds a richer flavor.

Does this tart require baking?No—it's a no‑bake dessert. Crust sets with chilling. Blind bake crust optionally for firmer texture.

How far ahead can I prepare?Make up to 24 hours before serving. Keep chilled until ready.

Can I make the lime‑cream topping vegan?Yes—use coconut cream and dairy‑free cream cheese alternatives.

Can I freeze leftovers?Yes, freeze covered up to one month. Thaw in fridge before serving.

What can I substitute for food coloring?Use natural powders like spirulina (green) or beet (pink) for clean color.

Can I use instant lemon pudding instead of custard?Yes—but homemade custard offers better texture and flavor balance.

Why does custard thicken strangely sometimes?Over‑cooking or inconsistent stirring can cause lumps. Whisk constantly and low‑heat.

Can I add gelatin to set layers faster?Yes—dissolve 1 tsp gelatin in warm water and stir into custard before chilling.

Can I omit the cream‑cheese topping?Absolutely—serve unadorned lemon tart for pure tangy flavor.
