1-First Step: Gather and prep your ingredients Set out all your ingredients before you turn on the stove. This is your mise en place moment, and it helps the process go smoothly. Juice the lemons, zest one lemon, separate the egg yolks if needed, and cut the butter into 6 pieces. Having everything ready keeps you from scrambling once the heat is on.

2-Second Step: Whisk the base In a medium heatproof bowl or a small heavy saucepan, whisk together the egg yolks, granulated sugar, lemon zest, lemon juice, and salt until the mixture looks smooth and well combined. The sugar should start to dissolve into the liquid. If you are using the thicker version with 2 egg yolks and 1 whole egg, whisk that mixture the same way. At this stage, the lemon scent should already be bright and fresh. That is one of the best parts of making homemade lemon curd!

3-Third Step: Cook gently over low heat Place the mixture over low heat, or use a double boiler for extra safety if you are nervous about curdling. Stir constantly with a whisk or silicone spatula. Keep the heat low to medium-low, around 170°F to 175°F if you are using a thermometer. The mixture should slowly thicken over 8 to 12 minutes. Watch for signs that it is ready: it should coat the back of a spoon and leave a clear line when you run your finger through it. Do not let it boil. High heat can make the eggs scramble, and that is not the silky texture we want. If your kitchen is busy, set a timer for 8 minutes and start checking from there. Stirring often is the secret to smooth lemon curd!

4-Fourth Step: Add the butter Once the curd has thickened, remove it from the heat. Add the softened butter pieces one at a time, whisking after each addition until fully melted and blended. This step gives the curd its glossy finish and rich flavor. The texture should look smooth, creamy, and slightly thicker than pudding. If you want an extra silky result, strain the curd through a fine-mesh sieve into a clean bowl. This catches any tiny bits of cooked egg or zest and gives you that bakery-style texture.

5-Final Step: Cool and chill Let the lemon curd cool at room temperature for about 20 minutes. Then cover it with plastic wrap, pressing the wrap directly onto the surface to keep a skin from forming. Chill it in the refrigerator for at least 2 hours before serving. It will thicken more as it cools. Serve it on toast, pancakes, scones, yogurt, cheesecake, or cupcakes. It also pairs beautifully with a slice of homemade quick bread like chocolate chip banana bread for a sweet, tangy surprise.
