I've made this before, it's a classic from
Joy of Cooking. To some degree, the grapefruit and avocado combine and make a bit of a dressing, but the recommended dressings are (they have a couple versions of the salad)
Tangerine-Shallot Dressing
1 peeled garlic clove
2-3 pinches of salt
1/4 cup fresh tangerine juice
2tbsp lemon juice
1 minced small shallot
2/3 cup vegetable oil (I always use EVOO)
Mash garlic and salt into a paste, whisk in everything but the oil, add oil in a small stream while whisking
Poppyseed-Honey Dressing
1/4 cup honey
3 tbsp fruit vinegar
1 minced small shallot
2 tsp Dijon mustard
1 tsp poppy seeds
salt and pepper to taste
EVOO
Whisk all ingredients except oil, add oil in a small stream until blended.
Celery Seed Dressing
1/2 cup sugar
1 tsp dry mustard
1 tsp salt
1-2 tsp celery seed
1 tbsp grated onion
1 cup vegetable oil
1/3 cup rice wine or cider vinegar
sprigs of lemon thyme
Combine the dry ingredients and add grated onion. Whisk in wet ingredients and garnish with thyme.
I think I used the citrus viniagrette when I did it. It's a surprisingly delicious salad, no?
