Hollandaise foam

Procedure
Bring the vinegar, shallot and peppercorns to the boil in a small pan, then reduce by half over a low heat. Strain through a fine sieve into a bowl, gently squeezing the shallot with a spoon.
Add the egg and the egg yolk and mix well with a whisk. Melt the butter in a small pan and bring to the boil. Gradually add the melted butter to the mixture, stirring constantly.

Put the hollandaise into a whipping siphon. Charge the siphon with a cartridge. Shake vigorously and keep warm.
