Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>If using whole butter, clarify it first: Melt the butter in a small saucepan over low heat without stirring. After a few minutes, you'll see the milk solids separate. Carefully skim the foam from the top, then slowly pour the clear yellow liquid (clarified butter) into a container, leaving the white milk solids behind. Keep the clarified butter warm but not hot (around 55°C/130°F).</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Fill a saucepan with about 5cm of water and bring to a gentle simmer. Choose a heat-resistant glass bowl that fits on top of the saucepan without touching the water (creating a double boiler). The steam will provide gentle, indirect heat to cook the eggs without scrambling them.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>In your glass bowl, whisk together the egg yolks and lemon juice until the mixture becomes pale and slightly thickened. This initial whisking creates a base for your emulsion by incorporating air and beginning to denature the proteins in the egg yolks.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Place the bowl over the simmering water (ensuring the bottom doesn't touch the water) and whisk continuously. The goal temperature for the yolks is about 65°C/150°F - they should thicken enough to leave a ribbon trail when the whisk is lifted. This process takes about 3-5 minutes. If the mixture starts getting too hot or thick too quickly, immediately remove from heat while continuing to whisk.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Once the yolks have thickened properly, remove from the heat. Now begins the crucial emulsion process: While whisking vigorously, add the warm clarified butter in a very slow, thin stream. Start with just a few drops, then gradually increase to a thin stream. This slow addition allows the fat to properly emulsify with the egg proteins. Continue until all butter is incorporated.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Add the Dijon mustard (if using), salt, white pepper, and cayenne (if using). Whisk to combine. If the sauce seems too thick, whisk in warm water, one teaspoon at a time, until you reach your desired consistency. The sauce should coat the back of a spoon but flow smoothly.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Taste and adjust the seasoning if needed, adding more lemon juice, salt, or pepper to your preference. The perfect Hollandaise has a balance of rich buttery flavor with a bright acidity from the lemon.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Serve immediately as Hollandaise does not hold well. If you must keep it warm before serving, place the bowl over a container of warm (not hot) water and whisk occasionally. If the sauce begins to separate or thicken too much, whisk in a few drops of warm water.</li></ol>
