Guacamole Potato Salad

3 pounds red potatoes
2 tablespoons plus 1 to 1 1/2 teaspoons salt
1 ripe avocado, peeled
2 teaspoons grated lime zest
Juice of 2 limes (about 1/2 cup)
2 garlic cloves, crushed
1/2 cup chopped cilantro
2 tablespoons mayonnaise
2 celery stalks, sliced

In a large pot, cover the potatoes with cold water. Add the 2 tablespoons of salt and bring the potatoes to a boil over high heat. Reduce the heat to medium and simmer until the potatoes are tender, about 20 minutes or until you can pierce them easily with a paring knife. Drain them in a colander and allow to cool.

Meanwhile, puree the avocado, lime zest and juice, garlic, cilantro, mayonnaise, and remaining salt in a food processor until smooth. If the dressing seems too thick, add a tablespoon or so of hot water.

Cut the potatoes into bite-size chunks (leave the skins on) and place them in a large bowl with the celery. Scrape in the dressing with a rubber spatula and gently stir it all together. Serve immediately, or cover and chill. Serves 8 to 10.
