CHICKPEA "MAYONNAISE" WITH SWEET-TART ONIONS AND BASIL
Makes about 1 cup.
Note: Not your mother's hummus, this spread/sauce/dip combines chickpeas with vinegar-sweetened onions and garlic as the main trio of the recipe. Backup is done by paprika, cumin and peppers. Add this bold, tart-sweet and robust spread to sandwiches of sliced eggs, meats or any vegetables. It will last eight days in the refrigerator.
1 medium onion, diced into 1-in. pieces
1 large garlic clove, crushed
1/4 c. Spanish sherry vinegar, or cider vinegar, and more for later
1/2 tsp. freshly ground black pepper
1/2 tsp. ground cumin
