This creamy tarragon aioli tastes like a more elegant and stimulating version of tartar sauce. It's fabulous on these Lightened Up Fried Fish Sandwiches, as well as on cooked chicken and fish, crab cakes, roasted vegetables, steamed artichokes and blanched asparagus. It’s also delicious in chicken salad. If you can’t find fresh tarragon, swap it out for parsley, chervil or basil. For a vegan version use a vegan mayonnaise.
