Ingredients for Purple Potato Salad with Avocado-Chia Dressing
675g baby purple or red creamer potatoes, unpeeled, scrubbed, and quartered
1 1/4 teaspoons sea salt
1/2 Hass avocado, pitted, peeled, and diced
2 tablespoons freshly squeezed lemon juice (from about 1 small lemon)
120ml freshly brewed jasmine green or white tea, at room temperature
2 tablespoons plain yoghurt (not Greek yoghurt)
35g white chia seeds
1 garlic clove, peeled and minced
2 spring onions, green and white parts, thinly sliced on diagonal
1 medium celery stalk, thinly sliced on diagonal
1 tablespoon finely chopped fresh dill or coriander
How to make Purple Potato Salad with Avocado-Chia Dressing
Back to contentsPlace the potatoes in a large saucepan and cover with cold water. Add 3/4 teaspoons of the salt and bring to a boil over high heat. Cover, reduce heat to medium-low, and cook until potatoes are just tender, about 10 minutes. Drain potatoes, place in a large bowl, and chill in the refrigerator.
In a bowl, thoroughly mash the avocado with the lemon juice until smooth. Add the tea, yoghurt, chia seeds, garlic, a few drops of hot pepper sauce, and 1/4 teaspoons of the salt and whisk to combine. Let stand for about 20 minutes. (Makes 300ml avocado-chia dressing.)
Remove the potatoes from the refrigerator. Add the spring onions, celery, and the remaining 1/4 teaspoons of salt to chilled potatoes and gently toss. Smear the avocado-chia dressing onto four salad plates, creating a "bed" for the potato salad. Top with the potato mixture, sprinkle with dill, and serve.
