Creamy and tangy with a gorgeous lemon hue, lemon butter is also known as lemon curd and is an old-school spread that can be added to both sweet and savoury dishes. Easy to prepare, and totally addictive, you’ll find yourself whipping up a new batch of this recipe on a regular basis.
How to make lemon butter: key tips
This recipe uses the double boiler method. Whisk the eggs and sugar in a heatproof bowl so that they are well combined before placing it over a saucepan of barely simmering water (try a medium-low heat). Note that you don’t want the water too hot and bubbling, and it’s best that the bowl doesn’t touch the water in the pan. Be sure to whisk the mixture constantly so that it cooks evenly.
Now, it’s time to add the remaining ingredients, reduce the heat to low, and get ready to whisk for about 20 minutes (yikes!). It’s important to cook your lemon butter over a low heat as you want the mixture to slowly emulsify and not ‘scramble’, so don’t be tempted to turn up the heat to get the job done faster.
Your lemon butter will thicken as it cooks. It is ready when it coats the back of your spoon and running a clean finger down the back of the spoon creates a distinct line. This recipe makes about 2 cups of lemon butter.
Key ingredients in this lemon butter recipe
Lemons are clearly the key ingredient and you can use whichever variety you have at hand. It’s worth noting, though, that Meyer lemons are the sweetest and their juice will create an elegant smooth butter. Whatever variety you use, ensure you choose lemons with a lovely outer, as you’ll also need to use the rind in this recipe.
You’ll also need 4 large fresh eggs. Take these from a 700g carton, so that the eggs are roughly 58g each.
It’s best to use caster sugar for lemon butter, as it dissolves easily into the egg and butter mixture. And you can use either salted or unsalted butter – both would do the job.
