In Creole cuisine, rémoulade is the pride of the po’ boy: a veritable catch-all sauce of ketchup, mayo, mustard, Louisiana mirepoix and spices. In France, the sauce is more refined and its classic accompaniment is celery root. The basic formula for a rémoulade in both the motherland and southland milieu is: mayo, something pickled, herbs and spices. Our recipe is a vegan take on the French version, and we used it as a platform for a classic bistro salad of celeriac. Not familiar with this brute of a root? Don't be surprised when you go from grocer to grocer praying you can avoid a run to Whole Foods for these glorious dirt bombs. You will fall in love with this dish.
A friend of ours used to eat a similar treat as a child in the Loire Valley. When her père whipped up a batch, he’d let it sit for a day before serving. If you’ve got the time and savoir faire you should do the same and skip the blanching of the root for a more authentic version.
