This is perfect to bring to a potluck, or you can halve the recipe for less servings. Fresh crab is always best but if that’s not available near you, canned lump crab would do. For the corn, you can roast the corn on the grill, or if you are lucky enough to live near a Trader Joe’s, they sell roasted frozen corn which is such a convenience. A good tip, if you make grilled corn on the cob often and have leftovers, cut it off the cob and freeze it!
