Step 1 of 10:
Prepare asparagus: Divide the stalks into two bundles and tie them so that all the heads are at the same height. Cut off the ends exactly 2 cm and save them for the broth.
Step 2 of 10:
Clarify butter: Slowly heat the butter until it turns golden brown and smells nutty. Pour it off immediately and let it cool slightly – this is the base for a stable hollandaise.
Step 3 of 10:
Prepare aromatics: Pluck and finely chop the tarragon. Zest the blood orange, and strongly reduce the juice separately.
Step 4 of 10:
Set up a double boiler: Gentle heat. No boiling. This is where the emulsion will be created later. At this moment, you know: You are ready to make a homemade hollandaise sauce that doesn't separate, doesn't curdle – but holds.
Step 5 of 10:
The asparagus broth: This broth is your foundation. Take your time with it. Bring water to a boil in a wide pot and season it with salt, sugar cubes, and 1 tbsp butter. Add the asparagus ends and let everything steep for 20 minutes. No vigorous boiling – you want to extract flavors, not tear them apart. Remove the ends and carefully place the bundled asparagus stalks in the pot. The tips must be completely covered so they cook evenly. Now think ahead: Ladle out 100 ml of hot broth and keep it ready. It's the key to your hollandaise and Manchego cream.
Step 6 of 10:
Clarify butter: A good hollandaise starts long before the egg yolk. Slowly heat 125 g of butter without stirring. Watch as the whey separates and the butter turns golden brown. As soon as it smells nutty, remove it from the heat immediately. Pour it through a fine sieve and let it rest briefly. It should be warm, not hot. This moment determines stability and depth.
Step 7 of 10:
The orange: Reduce the orange juice strongly until it becomes syrupy. This is where concentration is created, not sweetness. Briefly blanch the orange zest in hot water, drain it, and pat it dry. This preserves the freshness without bitterness. Set both aside within easy reach.
Step 8 of 10:
The hollandaise sauce: Your focus counts now. Whisk the egg yolks in a metal bowl. Incorporate 50 ml of hot asparagus broth and place the bowl over a gentle double boiler. The water must not boil. Whisk the mixture constantly until it significantly increases in volume. Now, incorporate the clarified butter spoon by spoon. Only when everything is combined, add the next spoonful. Season with salt and a hint of cayenne. Stir in the reduced orange juice and zest. The tarragon goes in at the very end. Your sauce is perfect when it stands creamy and coats the spoon.
Step 9 of 10:
Manchego cream: The deliberate counterpoint – this cream is not an extra, it adds depth. Bring the cream to a boil and reduce it by half. Add 50 ml of asparagus broth and let it steep briefly. Puree the mixture with the finely grated Manchego until smooth. The consistency should be soft: spoonable, not heavy.
Step 10 of 10:
Check for doneness: Pierce the asparagus head with a knife. If it slides in without resistance, it's perfectly cooked. Carefully lift the asparagus out, remove the strings, and let it drain briefly. Now everything is ready for the next moment: serving.
