Prepare your ingredients by cutting butter into small chunks, whisking the eggs and egg yolk together and juicing and zesting the lemons.
zest of 1-2 lemon, 2 large eggs, 1 large egg yolk, 100 g block butter (salted or unsalted), 2-6 tablespoon lemon juice
In a small pan, mix together elderflower cordial, lemon zest and juice. Taste and add more zest and lemon juice if required and adjust sweetness with sugar (if needed).To choose the right lemon to elderflower ration for you I would suggest starting with zest of one lemon + 2 tablespoon of lemon juice and mixing that in a bowl with 100ml elderflower cordial. Have a little taste and adjust from there - perhaps add zest of another lemon, more lemon juice to make it tangier and sharper or a touch of sugar to make it sweeter. Once you're happy with the flavour combination of lemon to elderflower you can proceed with recipe. ***Quick Tip*** Adjust the flavour with lemon or sugar but do not increase the amount of elderflower cordial. Also don't use more than 6 tablespoon of lemon juice. My Quantities - I used zest of 2 lemons + 5 tablespoon lemon juice + extra 20g of sugar on top of 100 ml elderflower cordial. More tangy than floral version for me. 100 ml elderflower cordial, zest of 1-2 lemon, 2-6 tablespoon lemon juice, 20 g caster or granulated sugar (optional)
Once you're happy with the flavour add butter and whisked eggs.
2 large eggs, 100 g block butter (salted or unsalted), 1 large egg yolk
Place the pan over a low heat or alternatively in a heatproof bowl placed over a pan with simmering water (bain-marie/double boiler method). Make sure the bowl doesn’t touch the water.Keep stirring all ingredients continuously until butter has melted and you get uniform mixture. I highly recommend using balloon whisk here. From that point on continue whisking for about 10 minutes (it will be slightly longer if using bain-marie method) until curd starts to thicken. The best indicator that your elderflower curd is ready is that it should coat the back of the spoon and not spread when you draw a line with your finger. ***Quick Tip*** Make sure to take the pan off the heat as you check for doneness. Once ready, pour the curd into hot, sterilised jars, seal with the lids and let them cool on the counter before storing in the fridge.
