Ingredients
• 1 recipe Classic Hollandaise Sauce, freshly made and warm
• ½ cup / 120 ml heavy cream, cold
• ¼ to ½ tsp / 0.5 to 1 g hot paprika
• OR ½ tsp / 1 g sweet paprika plus ¼ tsp / 0.5 g cayenne pepper
• Salt, to taste
Instructions
1. Prepare the Hollandaise Sauce using your favorite recipe. Ensure it remains warm, but not piping hot, while you proceed with the next step.
2. In a separate, chilled bowl, use a hand mixer or whisk to beat the cold heavy cream until it forms stiff, firm peaks.
3. Gently fold the whipped cream into the warm Hollandaise sauce using a spatula. Work in thirds to maintain the airy texture, mixing until just combined and no streaks remain.
4. Stir in your choice of paprika (hot, or the sweet paprika and cayenne combination). Taste the sauce and adjust the seasoning with more spice or a pinch of salt if needed.
5. Serve immediately for the best texture and warmth. This sauce is divine drizzled over roasted vegetables or poached eggs.

Pro Tips
• for Perfect Mousseline
• Temperature is key. Your Hollandaise must be warm (not hot, or it will melt the cream) and your cream must be very cold to whip properly. This temperature contrast is crucial for a stable emulsion.
• Fold, don’t stir. Use a gentle folding motion with a spatula to incorporate the whipped cream. Over-mixing or vigorous stirring will deflate the cream, and you’ll lose that signature light, airy texture.
• Serve immediately. Mousseline sauce does not hold well. It’s best made just before serving to enjoy its delicate, cloud-like consistency. It cannot be effectively reheated without breaking.
• Spice it your way. Start with the smaller amount of paprika or cayenne. You can always add more, but you can’t take it away. Taste as you go to find your perfect level of warmth.
FAQ
Q: Can I make this Sauce Mousseline vegan or dairy-free
A: A true vegan version is challenging due to the butter, eggs, and cream. You would need to start with a vegan hollandaise (using plant-based butter and an egg yolk substitute like cashew cream) and then fold in a high-quality vegan whipping cream or the whipped solids from a chilled can of full-fat coconut cream. The flavor and texture will be different, but it can create a similarly rich and creamy sauce.
Q: What are the best vegetarian dishes to serve with Sauce Mousseline
A: This sauce is incredibly versatile for vegetarian meals. Beyond poached eggs and roasted asparagus, try it drizzled over steamed artichokes, pan-seared tofu steaks, roasted broccoli or cauliflower, or a hearty vegetable gratin. It’s also a luxurious topping for potato dishes like hash browns or roasted new potatoes, instantly elevating any vegetarian brunch or dinner.
Q: Can I make Sauce Mousseline ahead of time
A: Sauce Mousseline is best served immediately and is not suitable for making ahead. The delicate structure comes from the warm Hollandaise emulsion and the cold whipped cream. Upon cooling, the sauce will deflate and likely separate. Reheating will cause the emulsion to break and the cream to melt, resulting in a greasy, thin texture. For the best cloud-like experience, prepare it just before you plan to serve your dish.
