Lemon curd is just the beginning. Fruit curds can be made with citrus fruit, mango, passion fruit, and others. Easy to make and so versatile in the kitchen.
My custom cake business, Cake Art Studio, had a fairly large menu of cake flavors. One of the most popular was “Luscious Lemon“- lemon cake layered with lemon curd and lemon mousse. It takes a lot of lemon curd to fill a 5 tier wedding cake, so we made quarts and quarts of the stuff. Of course this means zesting and juicing lemons by the case. I always felt bad if I got a new intern and one of their first jobs was to zest the lemons. They probably thought it was some kind of mean initiation.
For something with such a frankly unappealing name, curd is one of my favorite go-to ingredients for a wide variety of desserts. I mentioned that I use it as a cake filling, but curd also makes a great tart or pie filling, can be used as the base for mousse or to sandwich French Macarons, is traditional on a scone with clotted cream and is insanely decadent warmed up and poured over ice-cream.
Citrus juices make great curd, but passion fruit is one of my favorites. The floral tropical flavor really comes through. For my business I buy frozen passion fruit juice. Unfortunately, that’s not something you’re likely to find in the grocery store. You can juice the fresh fruit. It’s a bit of work, and passion fruits can be a little expensive, but if you’re looking to make a tart or cake with an unusual flavor, I think it’s well worth the effort.
I use the same basic recipe for all my fruit curds, just changing the amount of sugar based on which fruit I’m using. The gelatin is optional. Instructions for blooming gelatin can be found here. If you’re using the curd for a spread or sauce you don’t really need the gelatin. Use the gelatin when you don’t want the curd to be too oozy, like in a cake or tart that will be sliced.
The curd will start out with a watery consistency and have a fine white foam on top. As it cooks it will thicken, the white foam will dissipate and the curd will become more translucent. Cook until the curd is very steamy, but not boiling, and it coats the spatula or spoon.
The recipe makes about 3 cups of curd.
