Chowhounds have been sharing some of their favorite sauces for artichoke dunking:
• Melted butter: plain, with lemon, or with lemon and shallots
• Mayonnaise: flavored with curry, chipotle, or roasted garlic
• Dijon mustard thinned with cream
• Yogurt with crushed garlic and lemon juice
• Tartar sauce
For cold artichokes, Sharuf lets hollandaise sauce cool to room temperature, then stirs in half as much sour cream and seasons to taste with mustard. You can make this ahead of time and refrigerate it, as it won’t harden up when chilled like plain hollandaise.
