AVOCADO, ORANGE, AND JíCAMA SALAD

Steps:

• With a sharp knife cut peel and pith from oranges. Working over a bowl, cut sections free from membranes and squeeze enough juice from membranes to measure 1/4 cup. In a bowl whisk together orange juice, curry powder, salt, cumin, sugar, and vinegar. Add oil in a stream, whisking until emulsified. Peel jícama and halve lengthwise. Thinly slice jícama crosswise and add to vinaigrette, tossing to combine. Halve, pit, and peel avocados and thinly slice crosswise.
• Lift jícama from vinaigrette and arrange on 4 plates with orange sections and avocado. Pour remaining vinaigrette over and around salads.
