possibly tartar sauce. maybe sauce tartare

Anyway, like mayonnaise from scratch, with mustard, olive oil and white wine vinegar, and with finely chopped gherkins, capers and parsley in.  It said ‘some’, so I don’t know if it was the right amount. 

This is meant to go with fish, but usually if we’re cooking fish, we don’t have time to make tartar sauce from scratch, and if we have time to make the sauce, we’re not having fish.  So I gave up, made it today and we had it with John’s dinner of sausages, potatoes, carrots and sweetcorn.  It tastes okay, is piquant, and would have gone better with fish.  But I expect it makes a nice potato salad, since my potato salad usually has mayo and gherkins, so is halfway there anyway.
