Any recipes for a shellfish free clam dip? Can still contain other seafood

My dad developed a shellfish allergy in his 50s after getting the flu. He misses lobster (obviously) but says that clam dip is what he misses the most. It's always been a staple around the holidays growing up in Maine and I'm just wondering if there's a way to get something somewhat similar to that flavor. Any ideas? He can still eat seafood that isn't shellfish
