There are several sauces that go well with crab cakes. Here are some options:

1. Remoulade Sauce: This is a creamy, rich, and savory sauce with a kick of spice that pairs well with any fried seafood. It is a popular dipping sauce for seafood and has different variations throughout the world. One of the most popular versions is Louisiana-style remoulade, which is made with creole style mustard, creole seasoning, and/or hot sauce.

2. Tartar Sauce: This is a classic sauce that is often served with seafood. It is made up of just a few ingredients, typically mayonnaise, capers, and sweet pickles. It is a great option for those who prefer a milder flavor.

3. Old Bay Sauce: This aioli sauce features the authentic and true Maryland flavors of Old Bay seasoning, fresh lemon, creamy tartar sauce, and Worcestershire sauce. It pairs well with seafood, especially crab cakes, and contains a healthy amount of tang from the lemon juice and a nice hint of spice from the cayenne pepper.

4. Lemon Butter Sauce: This is a simple sauce made with butter, lemon juice, and herbs such as parsley or chives. It is a great option for those who prefer a lighter sauce that wont overpower the flavor of the crab cakes.

5. Cocktail Sauce: This is a tangy and slightly spicy sauce made with ketchup, horseradish, Worcestershire sauce, and lemon juice. It is a classic dipping sauce for shrimp cocktail, but it also pairs well with crab cakes.

6. Aioli Sauce: This is a garlic-flavored mayonnaise that is often served with seafood. It is a great option for those who enjoy a strong garlic flavor.

7. Mustard Sauce: This is a tangy and slightly sweet sauce made with Dijon mustard, honey, and mayonnaise. It is a great option for those who prefer a sweeter sauce that still has a bit of tanginess.

Ultimately, the best sauce for crab cakes is a matter of personal preference. Some people prefer a tangy and spicy sauce, while others prefer a milder flavor. It is recommended to try a few different sauces to find the one that you like best.
