1. Prepare Your Ingredients

Start by zesting your lemon (if you’re using zest) and squeezing the juice from it. Set both aside. Crack the eggs into a microwave-safe bowl and whisk them lightly.

2. Combine the Ingredients

In the same bowl, add the fresh lemon juice, sugar, and butter cubes. Whisk everything together until the mixture is smooth. If you’re using lemon zest, add it to the bowl now.

3. Microwave the Mixture

Microwave the mixture on high for 30 seconds. After 30 seconds, remove it from the microwave and whisk it well. This step helps to break up any clumps that may have formed and ensures a smooth consistency.

4. Repeat the Microwaving Process

Continue microwaving in 30-second intervals, whisking between each interval, until the curd thickens to the consistency of a custard. This usually takes about 2-3 minutes. Keep a close eye on it to prevent overcooking.

5. Cool the Lemon Curd

Once the curd has thickened to your liking, remove it from the microwave. Let it cool in the bowl for a few minutes before transferring it to a jar or container to finish setting. The curd will continue to thicken as it cools.

6. Enjoy!

Your microwave lemon curd is now ready to be enjoyed! Spread it on toast, swirl it into Greek yogurt, or use it to fill a tart or cake. The possibilities are endless!
