4 Lemons, 4 eggs, 350g caster sugar, 8oz butter, rosemary.
Lemon curd is already glorious, so thick and silky with that most mouthwatering flavour, but adding rosemary to the mix gives it an almost undetectable extra dimension that seems to make it even more lemony somehow without being too tangy or bitter. This makes a wonderful present, as rosemary is a symbol of love and loyalty. (yes, I meant to post this before Valentine's Day...)
1) Measure out the sugar and pour over three sprigs of rosemary. Leave to macerate overnight.
2) Juice the lemons, pour into a pan then pluck the rosemary sprigs from the sugar and allow to infuse with the lemon juice for 5 minutes.
3) Whisk the 3 eggs and one yolk together in a mixing bowl and set the bowl over a pan of boiling water to make a bain marie.
4) Add the rosemary infused caster sugar to the eggs with the rosemary infused lemon juice. Whisk until you cannot see any sugar grains, then add half of the butter and stir through.
5) Leave on the hob, whisking occasionally until the lemon curd is thick enough to draw a line through it with a spoon. Take from the heat and whisk through the remaining butter to make it glossy, then pour into hot, sterilised jars and allow to cool completely before consuming.
