As winter salads go, it’s a combination of two fruits you’d never think belong together — avocado and red-fleshed grapefruit. Not pink grapefruit — but red, redder, reddest. The cravings start now, as red grapefruit and avocado appear in stores at the same time, November through April.
The story of this odd combo starts in South Texas, a region with a year-round temperate growing zone and fertile soil enriched by the Rio Grande. The grapefruit and avocado pairing’s origin might be as simple as rhubarb and strawberries sharing a season and ending up in pie together. Or the now-cordial association of summer tomatoes with watermelon. Could it be that South Texas locals, faced with two major simultaneous crops, may have had an inevitable epiphany based more on the avocado than the grapefruit?

The evolution of grapefruit’s redness
Grapefruit isn’t all that versatile. But avocado lovers will stick an avocado into a chicken dish, on top of steak, inside an enchilada, a burrito or a quesadilla. They’ll add chunks of it to a zucchini salad, sneak it into tuna fish, and mash it and use it as frosting on a Jell-O mold. Why not section a grapefruit and toss it with avocado slices? At the very least, the acid from the grapefruit will prevent the avocado from turning brown.
There was plenty of time for the grapefruit and avocado dish to evolve. The first grapefruits in South Texas were white. They got there by Spanish missionaries. In 1929, an accidental sighting of a red grapefruit hanging on a pink grapefruit tree amazed growers. Its flesh was so gorgeous that growers raced to breed redder bud mutations. So many South Texans were naming red grapefruit varieties after themselves that to end the confusion the term “ruby” was adopted for all.
The Ruby Red Grapefruit was the first grapefruit to hold a U.S. patent. Its offspring are trademarked. The Rio Star, which I buy in California, combines the two reddest varieties, Rio Red and Star Ruby. It’s seven to 10 times redder than the original Ruby Red. The Ruby-Sweet is three to five times redder than a Ruby Red. (Sunkist also grows red grapefruit in California and Arizona under the names Star Ruby and Rio Red, among others.)
High time for avocado
As to the avocado, also coming into production in South Texas, the variety there is Lula. It’s much bigger than California’s or Mexico’s Hass, weighing nearly a pound. But the flesh is comparable — buttery with 15% to 26% oil.
Depending on where you live, you’ll use the avocado available. In these pre-Super Bowl times, avocados presumed destined to vats of guacamole are piled high in stores and priced low.
To offset grapefruit’s acid, the typical dressing for grapefruit avocado salad trends sweet. The dressing turns pink from red onion and red wine vinegar, a suitable color for a really red grapefruit.
Grapefruit and Avocado Salad With Pink Poppy Seed Dressing
Serves 4 to 6
½ medium red onion, in chunks
½ cup red wine vinegar (not too darkly colored)
½ cup sugar
¼ teaspoon dry mustard or prepared Dijon
⅓ cup vegetable oil
⅓ cup olive oil
¼ cup fresh chopped cilantro leaves
⅓ cup fresh chopped mint leaves
2 tablespoons finely minced jalapeño, divided
1½ tablespoons poppy seeds
3 red grapefruits
3 just-ripe avocados (not too soft)
1. To make the dressing, in a blender or food processor, combine onion, vinegar, sugar and mustard. With machine running, slowly add all the oil. With one or two bursts, pulse in the prepped cilantro, mint, half the jalapeño, and poppy seeds. You should have about 2 cups.
2. Using a long sharp knife, slice off skin and all of the bitter white pith from each entire grapefruit. Holding the grapefruit in one hand and working over a bowl, cut in between the membranes to release the sections.
3. Squeeze the juice from the membranes into the dressing; discard the membranes.
4. Slice avocados ¼-inch thick. Arrange grapefruit sections and avocado slices on butter lettuce. Spoon dressing over the fruit. Squeeze lime juice over each salad. Sprinkle with remaining minced jalapeño and serve.
The dressing and the grapefruit may be prepared several hours ahead of serving, covered and refrigerated. The avocados and lettuce should be prepared just before serving.
