Chef’s notes
- The hollandaise technique with a tarragon reduction; use with steak, roast mushrooms or asparagus.
- When scaling, adjust pan or tin size and work in batches where needed; cooking and proving times follow texture and temperature, not the portion multiplier.
Keeping
Prepare immediately before service and discard leftovers; do not boil the finished egg liaison or emulsion.
