Ingredients and Preparation

Before we begin, let’s go over what you’ll need.

Ingredients (Yields 2 ¼ Cups)

• ½ cup (115 grams) unsalted butter – Melted and slightly cooled to help create a creamy texture.
• 1 cup (200 grams) granulated sugar – Essential for balancing the tartness of the lemons.
• 3 large eggs + 1 egg yolk – The extra yolk adds richness and helps thicken the curd.
• 1 cup (240ml) freshly squeezed lemon juice – Fresh lemons provide the best flavor; bottled juice can be too acidic or bitter.
• Zest of 1 lemon (about 1 tablespoon) – Adds a burst of fresh citrus aroma.

Ingredient Substitutions

• Butter alternatives – Use coconut oil for a dairy-free version.
• Sweetener swaps – Substitute honey, maple syrup, or powdered sugar for a different sweetness profile.
• Citrus variations – Try lime or orange juice for a unique twist on the classic recipe.

Step-by-Step Instructions

Step 1: Mixing the Ingredients

Start by selecting a large microwave-safe bowl—bigger than you think you need. The lemon curd will expand as it cooks, and a smaller bowl may lead to messy spills.

1. Whisk together the melted butter and granulated sugar in the bowl. The sugar should dissolve slightly as you mix.
2. Add the eggs and extra yolk, whisking thoroughly until the mixture is completely smooth.
3. Pour in the lemon juice and zest, continuing to whisk until fully combined. The mixture will look thin at this stage, but don’t worry—it will thicken as it cooks.

Step 2: Cooking in the Microwave

Now comes the easiest part—cooking the curd in the microwave.

1. Set your microwave to high power and cook the mixture in 1-minute increments. After each minute, remove the bowl and stir the mixture thoroughly. This ensures even cooking and prevents the eggs from scrambling.
2. Continue microwaving and stirring in 1-minute intervals until the curd thickens enough to coat the back of a spoon. This usually takes about 5 minutes, but times may vary based on microwave wattage.
3. Watch closely to prevent overheating, which can cause the curd to curdle or bubble over.

Step 3: Straining for a Silky Texture

Once the curd reaches the right consistency, remove it from the microwave and pour it through a fine mesh strainer into a clean, heat-safe container. This step removes any tiny egg bits and ensures a perfectly smooth, silky texture.

To prevent a skin from forming, press a piece of plastic wrap directly onto the surface of the curd. Let it cool completely before transferring it to the refrigerator.

Beginner Tips and Troubleshooting

Even with such a simple recipe, a few common mistakes can happen. Here’s how to avoid them.

1. How to Tell When the Curd is Done

• Dip a spoon into the curd and run your finger across the back of it. If the line stays, the curd is thick enough.
• The curd will continue to thicken as it cools, so don’t overcook it.

2. Preventing Lumps

• Stir well after every minute in the microwave to ensure even cooking.
• If lumps appear, simply strain the curd before storing it.

3. Fixing Overcooked or Scrambled Curd

• If the curd has scrambled egg bits, don’t panic—just pass it through a fine mesh sieve.
• To prevent this, use lower power in your microwave and stir more frequently.

4. If the Curd is Too Thin

• Microwave in additional 30-second increments, stirring well between each.
• Ensure you’re using fresh lemon juice and enough egg yolk, as these help thicken the curd.

Serving Suggestions

Now that you have a perfect batch of lemon curd, here are some delicious ways to enjoy it:

For Breakfast

• Spread it on toast, muffins, or croissants for a citrusy start to your morning.
• Swirl it into Greek yogurt or oatmeal for a bright and tangy twist.

• Drizzle over vanilla ice cream or cheesecake for an extra layer of flavor.

For Snacks and Tea Time

Storage and Freezing Tips

One of the best things about homemade lemon curd is that it stores beautifully.

Refrigeration

• Store in an airtight container in the refrigerator for up to one week.

Freezing

• Lemon curd freezes well for up to three months.
• Use a freezer-safe container, leaving some space at the top for expansion.
• Thaw overnight in the refrigerator before using.
