An impromptu breakfast at Wild Caper in Brixton has led me to a new summer obsession. Nestled in between the toasted sourdough, homemade jams and ricotta was a small dish of mellow yellow in the shape of proper lemon curd. Creamy as custard and bursting with the invigorating tang of sunshine soaked lemons, I fell in love with it. And went back the next week for more of the same. (Wild Caper doesn’t even advertise it does breakfast, but it’s the best in Brixton… you need to go there!)

I was tempted to buy a jar of it the third time I went in (this time for one of their sourdough doughnuts) but having found some proper unwaxed Italian lemons in The Fruit Garden in Herne Hill the day before, I postponed my original plans for limoncello and decided to make a vat of lemon curd instead.

I expected it would be delicious. I did not expect it would be easier than falling off a log to make it. The only remotely fancy thing you need is a bowl over a pan of water and a lemon zester or grater. I followed this recipe from the lovely Rachel Eats as it seemed the most straightforward I could find. I halved the amount of sugar as I loathe sickly sweet citrus things and wanted some sharpness to it. It made about a pint of curd and filled a small Kilner jar.

Start by sterilising your jars in the oven. This is very important. Then get down to zesting and juicing your lemons as your (unsalted) butter melts above the water. Revel in the citrussy spell of summer now infusing your kitchen as you go. Add the lemon to the butter and put in as much sugar as you choose and make sure it is all melted. Double check the water isn’t boiling under the bowl and things aren’t too hot and then add in your eggs, whisking firmly and making sure nothing scrambles and then cook it out until it looks thick and opaque. Resist the temptation to stick your finger in there. It’s hot and you need to be fussy about good preserve hygiene.

Pour into your sterilised jar promptly, close the Kilner jar or cover with a lid and leave to cool. Scrape the bowl out and lick the spatula with unreserved glee. This stuff is amazing. Light, yet buttery with an utterly moreish tingle of lemon. You’ll be hard pushed to walk past the jar without dipping into it.

Dollop it on bread or Ryvita with a base of cream or curd cheese. Perk up your porridge with it. Stir it into yoghurt for a luxury dessert. Ripple it through ice cream. Give crepes a new lease of life. Take your lemon drizzle cake up a notch. Fill lemon poppyseed muffins with it. Eat it off the spoon out of the jar. Try to resist the urge to turn everything you come across into curd, even though you imagine grapefruit and passion fruit would both be sensational with the sharpness and sweetness that a good curd has. Make friends and influence people with jars of this when they invite you for instead of a mediocre bottle of wine from the corner shop. The possibilities are endless. But just make sure you make it immediately…
