"I cook the diced potato separately..."
veddy interestink . . . I 'over cook' Russets to use them as the "thickening agent"
basically I boil the potato until there is some "flourly decomp" - then proceed with adding seafood stock + pre-done bacon/onion etc....
essentially I use the potato to replace the roux, make up the body and season, then . .
fresh shucked clams get a rough chop and go in last . . .
may not 'work' in a commercial setting? except, , , , one cannot "hold" cooked clam bits/strips/chopped for any length of time without making "clam gummies" - no?
