Turkish sumac powder, known as sumak, is a vibrant reddish-purple spice ground from the dried berries of the Rhus coriaria shrub. It is a staple in Turkish and other Middle Eastern and Mediterranean cuisines, providing a tangy, lemon-like flavor with a hint of earthy fruitiness. Unlike lemon juice, sumac provides a bright acidity without adding liquid and has a milder, more rounded sourness. Net Wt. 4oz
