Ingredients for a double batch:
4 large sweet oranges (zest)
2 tbsp of the juice of the sweet orange
10 tbsp Seville orange juice - about 4 large oranges
2 tbsp lemon juice
450g sugar - about 2 to 2¼ cups depending on which website you believe. I used 2 cups.
230g butter - 1 cup
4 eggs
Containers to hold approximately 600g of curd- Put the rind (grated carefully to avoid the pith), juice, butter and sugar in a bowl, sat in a saucepan of water.
- Turn on the hob (you can tell this recipe is not from North America) and bring the water up to a gentle bubble, stirring the contents of the bowl until the sugar has dissolved.
- Add the beaten eggs to the bowl and continue to stir. It may take up to half an hour for the curd to reach the consistency of custard. It is ready when the mix will stick to the back of a metal spoon.
- Take off the heat, leave to cool slightly and then spoon into sterile containers.
This shows how much juice I squeezed from four Seville oranges. Three weren't enough to yield 10 tablespoons' worth.
My makeshift double boiler - a pot inside a larger pot of water.
The recipe doesn't mention tempering the eggs. I found it worked better to add the beaten eggs to the mix and heat it all up together. Still, I strained the mixture - twice for good measure.
Even though the liquid sticks to the back of the spoon (not shown) and is thickening, I'd still like it a little thicker.
The curd can be jarred, although I understand it doesn't last as long as jam, and you can make tarts or pies with it. I did attempt, once, to carry on to make the pie mentioned in the recipe but my pie shell and meringue were disasters.
One day, I should make lemon curd and see if I can taste any difference between it and the orange curd.
