Gravy mayo

A Sandwich Shop staple. When you are cooking meat, be it a stew or a roast, keep some of the cooking liquid. Sieve it. And reduce it in a pan until it is a tbsp or two of thick, rich, sauce and then add this to a batch of the Perfect Mayonnaise. You can simply beat it in at the end and if it’s warm, it mixes in better. Read the Braised Beef For All Seasons recipe for further musings on this little legend.
