ABOUT THIS RECIPEBitter, creamy and a little fiery
This appetizer is all about contrasts that balance one another. Grapefruit brings bright acidity and a little bitterness; avocado makes everything creamy, while the shrimp add a mild, briny flavor. Chili and lime juice give the dressing a kick and a bit of heat. Toasted corn adds a sweet note and a firm bite, so the dish isn’t made up of only soft segments and shrimp. Taste the grapefruit first: if it’s very bitter, use a little less and add a pinch of salt to the dressing.
Grapefruit is generally easy to find in the colder months, but this combination also works outside citrus season when you can find firm, ripe fruit. Choose an avocado that yields slightly when you press it gently but doesn’t feel mushy. Raw, peeled shrimp are handy here: they cook in just a few minutes. If using frozen shrimp, thaw them completely and pat them very dry. Otherwise, the moisture will cool the pan, and they’ll steam rather than brown.
A hot skillet is important for the shrimp. Cook them in a single layer and give them a short time to color lightly on the outside; as soon as they’re opaque and curl up firmly, take them off the heat. Cooking them for too long makes them tough. Toast the corn separately in a dry pan, so the kernels develop brown spots here and there without turning soft. Fresh corn kernels have the firmest bite, but drained canned corn works too: pat it dry before toasting.
Cut the grapefruit into segments just before serving, and add the avocado and dressing at the last moment too. Citrus can discolor the shrimp and avocado, and leave a lot of juice on the plate if everything sits together for too long. You can mix the dressing ahead of time, but keep it separate and stir it again just before using. Serve small portions on chilled plates as an appetizer, or put the dish on the table with bread and extra corn for a light lunch. Leftovers with avocado and citrus are best right after assembling; cover any shrimp that haven’t been served and store them in the refrigerator, then eat them within two days.
