From the Test Kitchen

It’s pie time! Recipes for crostata (an Italian, open-faced pie or tart) date at least as far back as the 15th Century. These delicious pies were traditionally made with a mix of sweet and savory ingredients and included fresh, seasonal produce. We’re keeping true to these early versions and making ours with briny olives and feta, peppery arugula, heirloom tomatoes and the rich sweetness of caramelized onions.

Prepare the ingredients:
1 Prepare the ingredients:
Preheat the oven to 425°F. Wash and dry the fresh produce. Using the flat side of your knife, smash the olives; remove and discard the pits, then roughly chop the olives. Cut the tomatoes in half lengthwise. Peel and thinly slice the garlic and onion.
Caramelize the onion:
2 Caramelize the onion:
In a medium pot, heat 2 teaspoons of olive oil on medium-high until hot. Add the onion. Cook, stirring occasionally, 6 to 8 minutes, or until completely softened. Reduce the heat to low and cook, stirring occasionally, 8 to 10 minutes longer, or until thoroughly caramelized and golden brown.
Make the dough:
3 Make the dough:
While the onion caramelizes, dust a large sheet pan with a pinch of the all-purpose flour. In a medium bowl, combine the whole wheat and remaining all-purpose flours with a pinch of salt. Stir in 4 tablespoons of olive oil and ¼ cup of cold water until a dough forms, being careful not to over-mix. Transfer the dough to the prepared sheet pan.
