Bearnaise sauce

I’ve made custard very successfully using the precision oven. Is there a recipe for using it to make Bearnaise sauce? Thanks!

YES! This is a traditional sous vide recipe, but works great in the APO. Time and temp will be the same in sous vide mode using 100% steam! Sous Vide Bearnaise Sauce

In making a sauce recipe like this do you still put the ingredients in a bag or can you just place them in a bowl in the oven? Thanks

Either way! No bag needed though
