abstract:Remoulade or rémoulade, invented in France, is a popular condiment in many countries. Very much like the tartar sauce of some English-speaking cultures, remoulade is often aioli- or mayonnaise-based.
The vegetable's most classic employment is in the cold French salad celerie remoulade, in which the root is peeled, grated, "cooked" in lemon juice (or blanched briefly in acidulated water) to lose a bit of its rawness, then dressed with a mustardy mayonnaise.
