You can buy ready made remoulade, but this is one of those sauces that so easily becomes a dumping ground for cooking industry waste. By making my own I know what's in it.
Finely chop your capers. My oldest use to call them claspers. 😄
Dry of your cucumbers so the brine don't dilute the sauce.

Home made mayonnaise, my own curry mix, turmeric, mustard and sour cream.
All in and stir.
Leftover meat made more interesting. The sauce will keep for a week in the fridge.
