Why Lemon Curd Is So Popular
Bold sweet-tart flavor
Smooth, luxurious texture
Incredibly versatile
Simple ingredients
Mastering this classic means you’ll always have a dessert upgrade ready, which is why so many cooks search for the perfect lemon curd recipe every time – here’s how!
Essential Ingredients for Perfect Lemon Curd
Quality ingredients make all the difference.
Core Ingredients
Fresh lemons (juice + zest)
Eggs (whole eggs or eggs plus yolks)
Granulated sugar

Why Fresh Lemons Matter
Bottled lemon juice lacks the brightness and aroma that fresh zest provides. For the best flavor, always zest your lemons before juicing.
Choosing the Right Lemons
Not all lemons are the same, and choosing well helps guarantee success.
Eureka or Lisbon lemons: Widely available, bright and sharp
Meyer lemons: Sweeter and less acidic (great if you prefer a milder curd)
For classic results, standard lemons deliver that iconic zing you expect from a perfect lemon curd recipe every time – here’s how!
Equipment You’ll Need
You don’t need anything fancy—just a few basics:
Heatproof bowl or saucepan
Whisk
Fine mesh strainer
Zester or microplane
Optional but helpful:
Double boiler (or a bowl over simmering water)
Kitchen thermometer

Ingredients
¾ cup (150g) granulated sugar
Zest of 2 lemons
½ cup (120ml) fresh lemon juice
4 large eggs

This usually takes 8–10 minutes.
Step 5: Add Butter
Remove from heat and whisk in butter cubes until fully melted and smooth.
Step 6: Strain for Smoothness
