a potato salad recipe

(The easiest of several owed posts.)

Dice into 1/2-inch cubes and boil until done, about 10 minutes:
2 large sweet potatoes
1 large potato

Drain and cool.

Mix together to make dressing:
Mayonnaise, 2-3 tbsp
Fig balsamic salad dressing or similar, about 1 1/2 tbsp
(If the people eating can have onions and chili, tamarind chutney could be good here too. Something tart and fruity.)
Salt, about 1/4 tsp
Freshly ground black pepper, about 1/2 tsp
Five spice powder, tiny pinch
Spicy brown mustard, about 1 tsp
Dried thyme, 1/2 tsp

Add about 1/4 cup frozen peas to the potatoes and fold in dressing until well mixed.

Optional slightly weirder ingredients that were very good:
One diced apple (treated with lemon to avoid browning)
Nasturtium flowers
