This tangy potato pickle is a Tamil pantry staple. "Thokku" refers to its thick, spreadable consistency. Fun fact: Traditionally prepared in summer for year-round use - the oil and tamarind act as preservatives. The potatoes absorb the spicy-tamarind flavors beautifully. Modern versions might include roasted garlic for depth. Served with idli, dosa, or as sandwich spread. The sesame oil used gives it a distinctive aroma. A little goes a long way - packed with bold flavors. Perfect to jazz up simple meals.
