Mayonnaise

To make a successful mayonnaise, have all the ingredients at the same temperature.

Stand a large, deep bowl on a tea towel to make it stable. Whisk the egg yolks, mustard, white pepper and salt in the bowl until evenly combined.

To begin with, whisk in a thin stream of oil until the mixture thickens. If the oil is added too quickly, the mayonnaise will separate.

After the first 100 ml (3¼ fl oz) of oil has been added, whisk in the vinegar. Add the remaining oil gradually.
