Ruby Grapefruit Curd

I have a rather special post in store for tomorrow. It involves a swoon-able Mother’s Day cake and this ruby grapefruit curd. There’ll also be caramel, frosting and flowers. All the things that make celebrating with cake, a necessary indulgence.

Some years back, my mom-in law shared her recipe for how to make a quick lemon curd with me. Since then, it’s the only way I make a curd. It does away with fussy double boilers and the risk of the mixture splitting. In the past, I’ve used it to make traditional lemon curd and a tart granadilla-orange curd. I’m intent making a blood orange curd this winter, but locally, these citrus beauties are rarer than hen’s teeth.

For today’s recipe, I’m opting for ruby grapefruit. It lends a slightly bitter note to the curd which I love. To balance the acidity, I’ve added lemon juice. Its sour character brightens and lifts the taste. Then, and this is an important step, I reduce the juice to concentrate the flavours and to yield a nett volume of 80ml. To thicken and enrich the curd, I add 2 whole eggs plus 2 yolks. The result is a lusciously creamy textured curd. Slather it onto sourdough toast for breakfast or serve with scones and cream for tea. Or, pop in tomorrow for a slice of Vanilla and orange cake with grapefruit curd.
