3-4citrus fruit of various kinds and sizes(oranges, grapefruits, pink grapefruits, pomelos, clementines, blood oranges and even kumquats are all good here - though stay away from anything too small and soft, like mandarins)
With a sharp paring knife, cut the peel away from the citrus, taking care to remove all the pith. Slice the citrus into ½-inch-thick slices. Slice the onion into half-moon crescents. Arrange the citrus and onion slices interchangeably on a big platter in several layers.
Chop pistachios and thyme roughly, and sprinkle over the fruit.
Shake or vigorously stir together olive oil, orange marmalade and lime juice until well combined. Pour liberally over salad.
Top with lime zest, smoked paprika or cayenne pepper. Finish the salad off with a generous sprinkle of Maldon sea salt.
NOTE: Spicy citrus salad pairs well with a Breakfast Martini cocktail.
