Grapefruit, Avocado & Pecan Salad

the Rio Grande Valley plate of three things the country grows: ruby segments cut free of every membrane, avocado, and toasted pecans, in a dressing built on the juice that runs out

Origin: Texas, United States

From the journey of Grapefruit.

This is a salad assembled from what the lower Rio Grande Valley and the country around it actually produce. Texas grows the red grapefruit it invented, the pecan is the state tree and native to the river bottoms, and avocados come up from just across the border. It is a modern plate rather than an inherited one, and it belongs to the same family of citrus-and-fat salads that runs through California and Mexico. Its logic is simple and worth stating because it governs every grapefruit salad. Avocado is fat with almost no acid and very little flavour of its own beyond richness; grapefruit is acid and bitterness with almost no fat. Each is improved by the other to a degree that neither is on its own, and the pecan supplies the third thing both lack, which is a dry crunch and a faint tannic bitterness that echoes the fruit. The technique that matters is supreming, which means cutting each segment away from the membranes that enclose it. Those membranes carry most of the naringin, so a supremed grapefruit is dramatically less bitter than the same fruit eaten from the half. It is also the step that makes the juice for the dressing, since what runs out of the carcass as you squeeze it is the only liquid the salad needs.

Ingredients

Salad

  • 2 large Ruby Red grapefruit
  • 2 whole ripe avocados
  • 80 g pecan halves
  • 0.5 small red onion, sliced paper-thin
  • 100 g watercress, or young rocket

Dressing

  • 3 tbsp extra virgin olive oil
  • 1 tsp honey
  • 1 tsp Dijon mustard
  • 1 tbsp cider vinegar
  • 0.5 tsp flaky sea salt
  • 1 pinch black pepper, freshly ground

Method

  1. Toast the pecans in a dry pan over a medium heat for six to eight minutes until they smell nutty, then tip onto a cold plate and leave to cool before breaking them roughly.
  2. Slice the top and bottom from each grapefruit so it stands flat, then cut the peel and all the white pith away in strips following the curve of the fruit.
  3. Holding the fruit over a bowl, cut each segment free between its membranes and let it drop. When only the membrane carcass is left, squeeze it hard over the bowl and set the juice aside.
  4. Lift the segments out of the collected juice and set them aside. Whisk the mustard, honey, vinegar, salt, and pepper into 3 tablespoons of that juice, then whisk in the olive oil.
  5. Slice the red onion paper-thin, rinse under cold water, and pat dry. Halve, stone, and slice the avocados just before serving.
  6. Spread the watercress on a wide platter, arrange the grapefruit and avocado over it, scatter the onion and pecans, and spoon the dressing over. Serve at once.

Notes

Ruby Red is the fruit to use, being sweet enough not to need sugar; white grapefruit works but wants an extra half teaspoon of honey in the dressing. Supreming is worth doing properly and takes about five minutes a fruit once you have the knack. Walnuts substitute for pecans acceptably, though pecans are sweeter and more appropriate. Common additions across Texas and the Southwest are crumbled queso fresco or feta, thin slices of jalapeño, and a handful of pomegranate seeds. Assemble at the last moment: the salad cannot be made ahead, since the avocado browns and the grapefruit weeps.
