Debbie’s Tip: Can’t find a barley rusk? No problem! Simply buy a large round loaf of crusty, bakery-fresh bread and slice it in half horizontally. If serving on a plate instead of in a bowl, cut a thin slice off the top half so that it will sit flat on the plate without tipping over. Brush the cut side of the top half with olive oil. Set the bottom half aside for another use. Toast on a baking sheet in a 400-degree oven until very crispy and golden, about 10 minutes. Watch carefully to make sure it doesn’t burn. To make the bread extra crispy, turn on the broiler for 1 or 2 minutes and crack the oven door slightly. Again, watch carefully because your bread can go from golden to charcoal in 10 seconds flat.
