An Enchanting Citrus Symphony

The Slow Cooker Lemon Butter (Curd) is a symphony of flavors, blending the sweetness of sugar, the zesty aroma of finely grated lemon rind, and the tartness of freshly squeezed lemon juice. These ingredients come together harmoniously to create a velvety and tangy curd that will leave your taste buds dancing with delight.

The Ingredients

8 Eggs (Whisked): The eggs form the base of this luxurious lemon butter, providing richness and a smooth texture.

1 1/2 Cups of White Sugar: The sugar adds sweetness to balance the tartness of the lemons and creates a luscious consistency.

3-4 Teaspoons of Finely Grated Lemon Rind: The lemon rind infuses the curd with a vibrant citrus aroma, enhancing its flavor profile.

1 Cup of Lemon Juice: The star ingredient, lemon juice, brings the tangy essence to this delightful spread. Make sure to juice fresh lemons for the best flavor.

250g Butter: The butter adds richness and creaminess to the curd, making it smooth and velvety.

Unleashing the Magic in Your Slow Cooker

Grating the Lemon Rind and Juicing the Lemons: Begin by grating the lemon rind, ensuring that it is finely grated to release maximum flavor. Cut and juice the lemons, ensuring there are no pips.

Whisking the Eggs: In a bowl, crack and whisk eight eggs until they are well beaten and combined.

Combining the Ingredients in the Slow Cooker: Pour all the ingredients, including the whisked eggs, into the slow cooker. This magical pot will work its wonders to transform the ingredients into a delectable lemon butter.

Melting the Butter: Turn the slow cooker on high heat and stir the mixture continuously until the butter has completely melted. The aroma of lemon and butter will fill your kitchen, creating an ambiance of anticipation.

Cooking and Thickening the Lemon Butter: Once the butter has melted, reduce the heat to low and place a tea towel under the slow cooker lid. Allow the mixture to cook for 1 1/2 to 2 hours or until the lemon butter reaches a thick consistency. Remember to stir the mixture every 20 minutes to ensure even cooking.

A Dash of Nostalgia

As the lemon butter simmers in the slow cooker, memories come flooding back to me. I remember my grandmother, with her hands stained with lemon juice, carefully crafting lemon curd in her kitchen. The aroma would fill the entire house, drawing us in with the promise of something extraordinary. Today, I carry on that tradition, recreating that nostalgic taste in my own home.

A Jar of Sunshine

Once the lemon butter has thickened to perfection, it is time to transfer it into jars. Carefully remove the jars from the oven and pour the golden curd into each one, filling them to the brim. Seal the jars with their lids, locking in the flavors of summer and sunshine.
