Asparagus with Lemon Sabayon
At Le Manoir we always follow seasonality using British asparagus which is at its best in May. The Lemon sabayon is a technique Raymond Blanc developed many years ago, which yields 3 times more than a classic hollandaise and 5 times less fat.
SPECIAL EQUIPMENT: A large balloon whisk and a stainless steel bowl.
1kg / 2 bunches English asparagus, medium thickness, woody stalks removed.
For the dressing
60g / 3 rgg yolks, organic/free range
60ml / 4 tbsp cold water
50g unsalted butter, melted, hot
1g / 1 pinch sea salt
1 pinch Cayenne pepper
10ml / ¼ lemon, juiced
In a large bowl whisk the egg yolks and water (*1). The mixture will expand 1 to 4 or 5 times the original quantity. Place the bowl over a pan of boiling water and continue to whisk until it becomes thicker (*2).
When the eggs are at a mayonnaise consistency remove from the heat and 2 continue to slowly whisk in the butter followed by the rest of the seasonings.
Pass through a muslin cloth and reserve in a serving jug or bowl.3
Trim the asparagus and cook in boiling water for 3-4 minutes, drain and 4 arrange on the plate.
To serve: Serve the asparagus with the lemon sabayon.
CHEFS NOTES
*1 The addition of water will increase the volume of the sabayon foam.
*2 You may be tempted to remove the sabayon from the heat as soon as it begins to thicken, but this may be too soon and the mixture will quickly deflate and separate. If however, you allow the temperature to rise above 80°C, the sabayon will be ruined and you will end up with scrambled eggs.
VARIATIONS
1 You can grill the asparagus and serve it with balsamic and shaved parmesan.
2 Poach asparagus and served with some wilted spinach and a poached egg.
3 This sabayon can be used as the basis for many other sauces: you can add herbs such as tarragon, basil and chives. Boil a finely chopped shallot with 4 tbsps of white wine vinegar until you have 1 tbsp left. Add it to the sabayon with some chopped tarragon to make Béarnaise sauce
