How to Make It
Bring a large saucepan of salted water to a boil. Add the carrots and cook over moderately high heat until tender, about 20 minutes. Drain.
Transfer the carrots to a food processor. Add the olive oil, vinegar, garlic, honey, harissa, cumin and ginger and process to a smooth puree. Season the dip with salt.
Scrape the dip onto a platter or into a bowl. Scatter the feta cheese and olives on top and serve.
Serve this dip with crackers or make your own pita chips: Split 8 pita pockets into two rounds. Brush the rough sides of the rounds with olive oil and sprinkle with salt. Stack the rounds and cut them into 8 wedges. Spread the pita in an even layer on large a baking sheet. Toast them in a 350° oven for about 10 minutes, or until crisp and golden. Turn the baking sheet halfway through baking to help them brown evenly.
