I bought some dried barberries at my Iranian market not too long ago and have been adding them to frittatas and salads. They’re tart dried fruits, about the size of currants. You can substitute dried cranberries or dried cherries for them.
02Meanwhile, strip the chard leaves from the stems (retain the stems if they’re wide and meaty) and wash well in 2 changes of water. Steam above 1 inch of boiling water for about 2 minutes, until wilted; alternatively, blanch for about 1 minute in salted boiling water. Transfer to a bowl of cold water, then drain and squeeze out excess water, taking the chard up by the handful. Chop fine.
03Dice the chard stems. Measure out 1 cup. Heat 1 tablespoon of the olive oil over medium heat in a medium skillet and add the chard stems. Cook, stirring, for about 3 minutes, just until crisp-tender. Add 1 minced garlic clove, stir for about 30 seconds, until fragrant, and remove from the heat.
04Combine the bulgur, chopped chard, chard stems, chopped tarragon and mint, za’atar, allspice and barberries in a large bowl. Whisk together the lemon juice, salt and pepper to taste, and olive oil. Toss with the bulgur mixture. Transfer to a platter or a wide salad bowl.
05Pound the remaining garlic to a paste with a pinch of salt in a mortar and pestle. Stir into the yogurt. Spoon on top of the salad and serve.
