Umami mayo recipe

Step by Step

Step 1

Combine the grapeseed oil and the bonito flakes in a small saucepan and cook over low heat until the oil reaches 180 degrees F. Remove from the heat and cool at room temperature for 20 minutes before straining through a fine mesh sieve. Reserve the bonito flakes for another use (see Cook's Note).

Step 2

Whisk the egg yolks together with the lemon juice, rice wine vinegar, and salt in a large bowl. Whisk briskly, then add the oil a few drops at a time until the egg mixture thickens and lightens in color a bit. Then, still whisking briskly, increase the oil flow to a constant, thin stream until a smooth mayonnaise texture is achieved.
